In no order, save for one:
Aquiel. It's bland, there's a forced plot twist that doesn't pay off because of the blandness.
Suddenly Human. There's hollow talk and a ton of screaming and a boring knife fight.
Bloodlines. Didn't they already do a "Ferengi seeks revenge on Picard' routine? It's still Bok, but the fake son unless the son isn't fake... meh. Season 1 did the revenge trope with Bok a lot better than an episode of "As the World Turns", anyway.
New Ground. Ugh. Horrible. What
@Oddish said.
The Outcast. Wasn't the "ishy natural procreation versus clean yet doped up test tube baby" debate more topical in 1980? (Yes, we've been told the original intent of this story's allegorical intent... which is fair, despite the story still missing the mark by a few parsecs. For the 3 people who didn't read up on that because they're only casual viewers, they're going to care even less.)
In Theory. Contrived and forced, it's an easy one to skip. Thankfully it's only a filler episode. "The Orville" did the shtick a lot better too, though in fairness it's a difficult concept to sell - human having an emotional relationship with an electronic device.
The Naked Now. A remake of "The Naked Time". Now, TOS had enough definition for characters when they delved into their mindsets in the original - never mind the one-off guest cast was given enough solid material for us to give a damn when he wants to stab himself to death. So, how does Naked Now try to improve on this? Everyone gets drunk and is thankful STIs were cured along with the common cold. A squandered premise, save for one scene with Geordi and another with Yar (before the point she bangs Data), this episode must have had the rest of the cast packing their suitcases in waiting and now half-hoping the show would be axed.
Justice. Like Code of Honor, there's a great premise that's squandered by bad rewrites and setting up another unintentionally racist bit (e.g. planet of the blonde hair/blue eye perfect people.) And when "bad rewrites" is said, look no further than the pre-credits opening and so much just glares. Along with everyone packing, they probably returned the props they pinched...
What
@Oddish said about "Code of Honor" is seconded by me. I think the story's plot has some potential, but it needed a few more rough drafts. Jessie Lawrence Ferguson still makes the story watchable.
This one is arguably worse:
Ethics. Season 5 was known for uneven handling of concepts, and this one just contrives to contrive to make the guest Doctor's viewpoint the eeeeeeevil one at every turn, with no reason other than dredging up phony and one-sided drama, with the actress is struggling to try to rise above the utterly faff material. (They didn't need to push the BS as the episode went on as well, and it was done to such an extent that I'm always in shock when someone opines "That should be Pulaski!" Erm, no, she was never like
that to begin with
, and her viewpoint didn't need to be villainzed so badly by the script dept either, if they wanted an intellectually honest discussion of the topics at hand.) It's just as awful how they conjure up Worf's magical survival, which is arguably worse, and certainly laughably bad. Hell, Dr Crusher could have even been more evolved and say "Your methods are horrible but they saved him, and I thank you for that since your work is at the core of this." instead of continuing the hyper-contrived elbow-high BS to the very end - unless Crusher preferred him dead, who knows. And maybe she does? How many people die paralyzed while she does her nose-up claim of "real research takes time." She must surely get one or two shattered spines every time a Ferengi ship zaps the ship with its disruptor array thanks to how those chemical barrels whose contents may be needed at a moment's notice are stacked, good grief... And in some cases, sometimes experimental treatments ARE allowed. Like cancer patients whose condition is otherwise impossible to treat and known treatments aren't working? Naah, contrive the episode to chalk up another case of "guest role is eeeeevil." for a cheap plot point to thrust up Crusher with. Sheesh, give me the likes of dumbing down the crew to make Wesley look smart in "Datalore" by comparison every time. This episode is so far worse with this...
Also, why Worf? They weren't going to pull another Tasha. No guest Klingon of the week to try to explore this that much more convincingly? It must also be a problem to re-stack all those booze barrels back up after every Romulan attack, too. DS9's "Sons of Mogh" took the ritual suicide routine and added far more to it, even if the ending was hokum. That hokum doesn't begin to compare with this episode's hokum.
