I've made it to Season 3.
I don't want this to be a long post, so I'll just briefly talk about the episodes I've seen, then talk about Season 2, and then do something about Season 3.
First Flight: This episode is very sentimental to me. When I was growing up, I was very much into Space Travel and I actually wanted to be an Astronaught. I just thought it was cool (Part of that love was Star Trek actually) and this episode I felt captured that spirit very well. I actually got a little emotional at the end when T'Pol named the nebula after AG.
Bounty: This episode really isn't worth discussing as it wasn't very good. The Tellerite part was decent, but the T'Pol in heat stuff wasn't. Also, I thought only the Vulcan Males had Pon Farr.
The Expanse: This has been the episode I've been waiting for. The start of Enterprise's new direction and it felt like the urgency was increased quite a bit. This episode had everything worthy of a perfect set up while being a great episode in it's own right. It ended the whole Duras story, and began the Xindi arc. I don't talk about scenery very much, this episode did awesome with it, showing the damage from the Xindi weapon to the scene against Duras was nicely done. I do wonder about the whole time thing (The Klingons never caught up to Enterprise in 7 weeks time?) but that's pits compared to what the writers were trying to do and I think it worked as a good finale.
The Xindi: Not the premiere I was expecting, but I was very glad to find out some tidbits that are important for the rest of the season. We found about about the Trillium D being insulation, and the 5 races of Xindi (And we got to meet them with some very nice CGI of the insectoids) but we also got the stupid Neuropressure scene (In place of the decon chamber I guess) and the old Archer get's captured in a trap and is taken prisoner. I'm reminded of the quote to End DS9, "The More Things Change, the more they stay the same." It's somewhat appropriate here.
Season 2 Overall
Well, that's a wrap for Season 2 and I think not a moment too soon. This season I thought was worse than Season 1, with some bad episodes like Canamar, A Night in Sickbay, Shockwave 2, Bounty, and Precious Cargo. Then you had the ho-hum episodes like Dawn, Marauders, Canamar again, and The Crossing. I thought this season did more meandering than Season 1 did, but maybe Season 1 was still new and fresh that there was that certain something that made it better.
With that said, there were still some pretty great episodes. Minefield and Dead Stop were the two first great episodes of the season, and I noticed the season got stronger at the end with The Breach, Regeneration, First Flight, Cogenitor and of course, The Expanse. Still though, the closer I got to Season 3, the more I couldn't wait for season 2 to be over. For that reason, Season 2 is my least favorite season of the show, and that's probably always been the case. Still, My top 5 episodes for this year in order are:
The Expanse
Cogenitor
Minefield/Dead Stop
First Flight
The Seventh (I know a lot of people don't like this episode, but I liked T'Pol's backstory)
In terms of character, I wish Mayweather had stayed on the Horizon. They don't use him very much and he really wouldn't have been missed. I also say the three best characters this year are T'Pol, Phlox, and Trip.
Season 3
So here we are at the Xindi Arc. I've been itching to see this season ever since I started watching Season 2. Looking forward to seeing if I like it more now than I did before. I've said that my problem the first time around was it didn't feel very Star Trek to me. It felt more like an action show that could have been it's own series. I'm not one to really care for Continuity so that really doesn't have anything to do with anything (And how many times has Star Trek in the last 45 years violated it's on timeline, with the first really bad example being in Assignment: Earth and the Enterprise going back just for "Research." Give me a freaking break regarding Canon.
Anyway, sorry for ranting, but this season is going to be interesting.
