I loved it. I'm not a big Sci-Fi fan at all, I prefer High Fantasy (dork v. nerd, right?), but my wife grew up on Star Trek so I went to see it with her. I thought the first reboot was good, and I thought this one was much better. I really liked this movie. I would classify it more action than Sci-Fi though.
All that being said, I never watched Star Trek on TV nor the original movies, though I did see the one with the whales as a kid. And I remember pretty much that it had whales.
So, for comparison purposes, I have nothing. I just watched this as a detached person looking for some action entertainment, and it passed with flying colors in that regard.
