Really, most of Generation's flaws can be boiled down to one thing: This movie should have been about the TNG cast, not about Kirk or anything else to do with TOS. The "passing of the torch" crap had been over and done with seven years before. It was completely unnecessary to involve TOS in this film other than the obligatory "Kirk meets Picard" schtick, which wasn't anywhere near as satisfying as it could have been if done correctly.
Well observed.
If a series--an alleged syndication success for
SEVEN years still needed to feed / catapult from the strength / pop cultural power of TOS, then TNG as a film series was almost doomed to fail. As it stands, no one talks about TNG movies, and certainly do not admit to a wealth of fond memories of the seriesm which launched on a sour, manipulative ("ooh! look, Trekkies--its Kirk!") note.
