Bottom Line: I liked the 2009 Star Trek because, while staying true to the Trek tradition and mythos, they created something really new, and I appreciated that. This one, it seemed like they were retreading ground that they'd already covered before. (Granted, being primarily a TNG fan, I've never seen The Wrath of Khan and most of the rest of them, so it was still a little new to me.)
--You can't keep asking Old!Spock for help every time you have a question or problem. That is cheating, and it's lazy.
--I think Spock yelling "KHAAAAAAAN!" after Kirk's mostly-death was the single most unintentionally hilarious Trek moment I've ever seen, including the introduction of the Ferengi in "The Last Outpost."
--To be completely honest, I had a hard time focusing on the plot after Kirk flagrantly and unabashedly flouts the Prime Directive at the beginning. I was like, "Wait a second; this isn't the movie I want to see. I want to see the movie in which he goes back and puts right his mistake; or at the very least, I want to see the movie wherein he returns to this planet many years later and sees the damage he's done to this culture and feels bad about it." Come on, even Sisko would have had the decency to feel at least A LITTLE BIT bad,[*](meaning he would spend a whole episode talking about how bad he felt about it, and then never mention it again) but Kirk is all, "La, la, la, who cares about pre-warp societies? I'm off chase some tail...literally!" To be honest, I was kind of glad when Benedict Cumberbatch started beating him up.
--Speaking of Benedict Cumberbatch, which is quickly becoming one of my new favorite hobbies, I thought he was terrific as always, but I felt that they really didn't give him enough to do.
--I'm not necessarily in favor of a TNG reboot, but if they ever decide to do it anyway, I want Benedict Cumberbatch to play Captain Picard. I know some people would complain about it, saying he couldn't or shouldn't play two iconic Trek characters, but there are plenty of actors who have played multiple roles across the franchise, and I'm willing to bet that most of the complaints would evaporate within the first 10 minutes or so of the movie, because he is just that good. Again, not that I'm in favor of a TNG reboot, but if they eventually do it, I just hope that they get the right man for the job.
--It was fun to watch this movie after binge-watching Sherlock, because when one of the Starfleet guys said, "Looks like we're dealing with a superman," I was quick to retort, "He's not a superman; he's a high-functioning sociopath. Do your research!"
