I thought that the film was good, but not great. It had an interesting plot and it's great to see all of the characters of TNG together again. It's a shame that they didn't mention the death of Jadzia Dax and show Worf confiding to his old friends about his loss. It would have been a nice nod to DS9. Overall, I thought it was a pretty solid movie and was better than:
Star Trek: TMP: zzzzzzzzz
Star Trek V: Good premise, great cast interaction, but the plot was a mess
Nemesis: Interesting premise, but the movie seemed so dull and lifeless as did the acting
ST 2009: All glam and glitter with little substance
