They very blatently say that it is an alternate timeline in the film, so as long as you go in with that knowledge and the normal Trek "anything can happen", you willl find the movie enjoyable.
This was the only thing that saved the movie for me.. them repeating that this was an alternate time line.
I still have problems with the design of the ship, however, given an alternate time line, I think I can live with this movie, however the new ship can never replace the true NCC-1701 U.S.S. Enterprise, the redesign was a bit too much and made the ship not all that attractive to me.
Overall, I give the movie 7 out of 10.. Ship design was a big - to me and reuse of content repetatively from TOS and TMP Movies which killed some of the originality.
To me it looked like they took TOS and TMP movies and crammed them all into 1.. I saw a lot of TOS, ST 1 and ST 2 in the movie (especially with the bug they put into Pike (Wrath of Khan), the early introduction of Checkov from TOS Season 2, the hidden attraction of Spock and Uhura from TOS season 2 - 3, the shot into the torpedo bay on George Kirk's ship (Wrath of Khan), the destruction of Romulus (Praxis from ST V), etc..)
I didn't buy a ticket.. a Friend bought a ticket for me and begged me to go (and took some alcohol to convince me to watch the movie).. I might go watch it again on my own to catch what I missed in the first run..
After all, it is an alternate time line.. thus might be an interesting reboot.
The movie was a bit too fast paced for my liking, but overall it was done pretty well. like I stated 7 out of 10 (couldn't get use to the sound of the ship doors.. where's the whoosh-boop? sounded more like chimes..)
