Watched this last night. Not bad at all.
At first I thought "wow, they finally figured out how to write Star Trek" the effects were spot on and the acting was remarkably well done. Then 3/4 of the way thru the movie it got dumb and we got the same ole same ole. I blame the writers lack of vision on that. I blame the marketing that thinks that we need to identify with the aggressor and justify their actions to sell movie tickets. The doomsday weapon had potential to be much more than what was portrayed.
Its like the writers, in seeking a grand finish to the movie, went stupid. Up until the last 3rd of the movie, the scientific concepts and portrayals of alien behavior promised something unique, then wham! Same ole same ole.
At 1/2 way, I recall thinking "This is how a Star Trek movie should be" then by the end I was sitting jaw-dropped thinking "what the hell were they (writers) thinking?"
The movie could generate massive amounts of speculation and discussion on a wide range of scifi subjects but most people will remember that piss-poor ending that everyone has seen play out time after time.
Just loved the eye candy and technology implications. Those alone make this film worth watching.
