Season one of The Orville is great, but my favourites in no particular order are
Mad Idolatry
If The Stars Should Appear
Firestorm
Majority Rule
About A Girl
Pria
I found season 2 a bit more entertaining.
Have they ever mentioned what past history is in the Orville universe as in what was their version of first contact in their universe?
First Contact when the humans joined the Planetary Union? Not that I'm aware of. Maybe in season 3.
Season 2 I've finished, up to "Identity" pt 2. I recall pt 2 being a downer but, wow, the show was never before this plot-by-numbers pedestrian; only the season 1 episode redoing "For the World is Hollow and I Have Touched the Sky" comes close, but that one still had stronger moments. I recall later episodes being generally better, save for one... until then:
Ja'loja: 5/10. The Isaac/Finn subplot is incredibly strong. And needs to be because the parody of "Amok Time" is incredibly weak. It's the weakest story of the season so far, does the season get any better?
Primal Urges: 9/10. Not too much Trek cribbing in this one, the arc for Bortus is pushed a little farther and is surprisingly engaging. If Trek was purloined, it doesn't readily show and that's a good thing because that means they're trying to really do their own thing. In this viewing, I suspect they took a nod to Klingons with ritual killing, but the concept goes back longer than that... and it's all used in a refreshingly different way that doesn't scream "plot by numbers" or "hey, this old Trek episode did it and a lot more interestingly".
Home: 10/10.
Alluring Kitten Alara Kittan (whose name is reminiscent of Emma Peel, Purdy, and other characters named in "The Avengers" from the 1960s so that little tradition of quirky double entendre names in quirky series continues) has to go home because of a debilitating condition. I want to drop a point because Alara was a cool character, but the plotting and acting and attention to detail are so gooooood and, dang, it's a dark story.
Nothing Left on Earth Excepting Fishes: 9/10. Nothing terribly wrong, this is yet another robust entry in this season that had me glued. Yeah, it's easy to see why the comedy is being sidelined but what makes up for it has been worth it so far. It's great they're following up with Teleya (whose pseudonym of "Janel TYLER" slipped right past me on initial viewing, so the reveal was that much more impressive. Not since The Portreeve has the old switcharoo trick been so effective.) The Gordon subplot is a little iffy at times, but nothing major.
All the World Is Birthday Cake: 7.5/10 A few plot points and oversimplifications don't do enough to ruin what is otherwise a shocking story. Both in originality, and going after astrology. I'm amazed the story didn't point out how stars and planets slowly shift position over time (e.g. our moon shifts away from Earth at approximately one long inch per year) so how they could rationalize the same notions centuries later as they always look at the stars with telescopes and mapping and never noticed... It's not implausible, but I dunno. But the story makes for any issues with solid acting with conviction by the actors and has proper moral points to play.
A Happy Refrain: 8.5/10. On first viewing this'll have anyone feeling tripped up with a huger WTFery. But there's a bizarre charm and every rewatch only has me liking the episode that much more. The comedy and humor are spot on and hilarious, and Orville actually succeeds in what TNG did not with "In Theory" and, more obviously, from "The Naked Now". Most points deduced because this is an episode one is more likely going to grow to appreciate, rather than loving it off the bat. But it's bold to revisit TNG concepts and more impressive as it worked. At least the ship's control panels are watertight. Not even going to think into that one and the story doesn't want you to because it wants you to say "Awwwwwwwwww" instead. And it didn't not work.
Deflectors: 8/10. A little weaker, but still a decent story - using a murder mystery trope too - and I appreciated what the story was trying to do with role reversals.
Identity: 9.5/10. It's too obvious that we know something big's going to go boom boom, but the music and acting more than make up for it. It's genuinely sad to see Isaac go, especially for the kids. I never understood how anyone thought "Kaylon are Borg" at the time as their backgrounds and motivations are so different, and by a width so big you can shove two solar systems through the gap... The revelation of mass extermination was outright horrifying and something we've never seen firsthand before. The Kaylon are more influenced by Cylons from the old Battlestar Galactica, and another change is that none of this involved or implied humanity. Much impressed. If anything, the BSery started toward the end as their claimed goal is to exterminate everything biological and yet they're also contriving to take prisoners to manipulate them. How will this conclude? Hmm...
Identity pt2: 2/10. Possible shark jumper. It's so "paint by numbers" and "connect the dots" and relying on part one's build-up and wave that it was inducing sleep at times. We see one Kaylon ship destroy an Orville-class ship with four blasts. The same size Kaylon ship later destroys a Krill vessel with two, if I recall... This is not just a problem of making the enemy "the big bad", since the song and dance in setting up subterfuge to throw Earth off guard doesn't make sense if all the Kaylon's enemies are this easy to exterminate. Come on. Plot development after plot development is right on cue. The EMP solution is even more BS, because nobody even began to have replacement parts for Isaac, much less any schematics to do the work with. It's not inconceivable that the ship itself would have shielding to prevent EMP damage, but how one can rig audible speakers to emit a sufficiently powerful EMP to (permanently destroy, these are walking circuit boards that don't "heal" or have "health") wipe out all the Kaylon yet leave critical ship components intact - nothing was designed ahead of time as a defensive measure. A battle that should have been in the Kaylon's favor based on the previous setup is somehow one that they lose thanks to joint efforts... of clearly weaker ships of which each can get destroyed after 2 to 4 hits, it still would have been no contest given the sheer size and power of the Kaylon. The episode also rushes closure with the reset button for later weeks as Mercer takes responsibility for the droid and Isaac apologizes to Claire and being alone (Primary's destruction cliche one-liner should have dramatic impact, but doesn't) and forgiveness and such and on with life they go. Maybe doing this one as a three-parter would have helped.
Okay, I have yet to see the remaining episodes, but from memory:
Blood of Patriots: 7/10. It's taking way too much from "The Wounded", but the introduction of Leyna (also quickly forgotten about later) and how her blood, when exposed directly to nitrogen, makes for a refreshing sci-fi style subplot that reminds that Orville can be more and other than a Star Trek rehash.
Lasting Impressions: 1/10. A painful and garbage copy of the TNG episodes with holodeck fantasies (read: Barclay, Geordi, Riker), which were done far more competently. It's pointless filler and the series is juggling rather a large number of arcs that are all far more worthy of development. It's not 1995 anymore where a 26 episode year can allow for one-offs. The technobabble used is pathetic. The items from the capsule are too pristine to be taken seriously. The episode painfully shows that humans in the 25th century act identically to those in the 21st, and yet one of the characters had the most unintentionally funny line of mentioning how they're so different in the future. I dare them to go back to 1600, 1066, or earlier, since at least prior to the 21st century the forms of communication were still evolving and not stagnating at a level that's arguably slightly de-evolved too, but this isn't English class or any language class so I'll move on: This episode makes Identity2 seem like 10/10 by comparison. Am adding 1 point for the cigarette subplot, as that was genuinely good, but I'd still say by far to scrap this episode and make Identity 3 parts to give it time to breathe and feel more authentic instead. Never mind a later episode using a variation of the theme of redoing things was used to far better effect.
Sanctuary: 8/10 Finally, a return to form. Great plot setup and execution. Huger plot arc move for the Moclans. If anything, at 10 episodes per season, rushing multiple arcs while still finding a one-off episode for pointless filler isn't doing much of a good thing. I probably would have held off on the Moclans and/or Krill and/or Kaylons and focus on just one, while keeping plot strands floating. Note that the idea of the Kaylon turning on the Union was originally to have been done in season 1 but was held back -- thankfully, as rushing that would have been a downer. I also recall the use of the song was a little overdone, but Family Guy was also known for keeping jokes running far longer than they needed and to be fair, if they're licensing the song it doesn't not make sense to use it as much as possible. Still, if Doctor Who from the 70s, 80s, and 00s licensed songs and used them for artistic flair, they knew when to turn the cassette player off. So, yeah, "9 to 5" was overused.
Tomorrow, and Tomorrow, and Tomorrow: 9/10 A couple weeks earlier we explored the notion of changing the past to change the future by using an egocentric person's still-working smartphone*, so now we're redoing it again. Only this time they're using creativity again and it's lovely to watch and be enthralled by. It also ends on a cliffhanger, and boom... I don't remember if it was this episode or an earlier one that that had Claire and Kelly chatting on what it's like to be single again.
* (if 8000nm-fabricated computers from 1974 begin to fail after decades of "regular use and storage" and the likelihood of failure increasing with each passing decade due to the pesky laws of physics, electromigration, etc, 20nm ones sold in 2015 where one RAM module became defective after two weeks seems less promising overall in terms of longevity, among other things...) /nerdMode
The Road Not Taken: 7/10. The different timeline more than ensured Earth is annihilated, down to even the microbes. What, no Kaylon is demanding they surrender for some "tactical advantage" again? Yes, it's shocking to see. Yes, it's shocking to see such inconsistency in the writing too. The floaty whizzy-bying Kaylon heads were unintentionally comedic, and may also have inspired a modern Doctor Who story to do the same for Cybermen (ugh). I was won over by the "let's hide in a black hole" subplot. Alluring Kitten is back again, it's great they got the actress back, but some of the dialogue and acting from all involved had a weird feel to it. Nice to see Evil Isaac. Everything is reset by the end, of course, with a cover-all line about how there might be subtle differences. It all feels slightly rushed, but holds its own - a pleasant surprise.
I will be rewatching these remaining episodes. I think I'll have better scores for Blood of Patriots and Road Not Taken. I anticipate the same scores for the others, but who knows. An episode one might have hated can be re-perceived later on if something was overlooked, or forgotten.... Or vice-versa. and that's part of the fun.
