Too much J.J. Abrams... too little Gene Roddenberry. If you are willing to suspend disbelief, and are just looking to escape for 2 hours, this is the movie for you.
If you are looking for a worthy prequel to one of the most beloved TV and Film franchises of all time, stay away.
The movie tried too hard to be clever, and sprinkle "Easter-eggs" throughout, I felt it was too comedic and sometimes almost "slapstick" to be taken seriously... think "Tribbles" not "Wrath of Kahn".
Acting was OK to good, plot was OK, it just never seemed to "gel" for me. The bifurcated time line allows J.J. Abrams unlimited creative license without ruining the "classic" Star Trek, I just wish he had done more with it.
