I think it kind of fits into the Star Trek universe- It's not the Enterprise, it's a "re-imagining" (not my words) of the Enterprise in a movie that was a "re-imagining" Star Trek...
It's grown on me a little as a starship design. Size issues aside (and I'm in the smaller ship camp), and comical looking nacelles, engineering (shit- on the Kelvin, people repelled on freaking ropes!!! WTF?), and bridge, I kind of like the ship...
Yes, I can rag on it, and kind of like it at the same time. And I'm still going to see the movie this up-coming week at the second run cinema... Fortunately the tickets are only $4!
