Look at how "All Good Things" ended it. That's how you end those characters' stories. That episode is like TNG's "Undiscovered Country". The films just ended on a tired and depressing note.
So in retrospect, the TNG movies punched me in the emotional gonads over what the TV series made me feel good over. So, another point for season 8.
This is a good point--the films did leave me feeling depressed, while All Good Things made me feel like their stories were going to continue. (Also, I felt the same way you did about seeing the Enterprise D and Data bite the dust.)
I've never made it though Nemesis, I have to admit. Given the choice, I'd really much rather watch almost any episode than one of the movies. I did enjoy First Contact, but I think that could easily have been the big two-part arc of an eighth season (without the bigger budget, but still, I think it could have been done). In fact, I remember being in high school when it came out--I asked a friend what he thought of the movie and his response was "that was a really good episode, but not much of a movie."
