I have to agree with a comment above about how TNG did not translate as well to the movie screen as it functioned on TV. I think TNG was more about the combination of diplomacy, examination of culture and ethics, and action all together in an equillibrium. Movies always rely far more heavily on action. TNG as a TV series never did, and when the movies were written that way--as they naturally would be--the essence of TNG really did get very lost. The TNG films never managed to accomplish the balancing act of a good plot and moments of the character chemistry that we enjoyed in the TV series, but the TOS movies certainly did all of that very well.
