Finales I Liked:
Star Trek: Voyager
Star Trek: TNG
Dawson's Creek: I too hadn't watched the show in a long time, but I cried through the whole episode.
Friends: Except for Ross and Rachel getting together (They were on a break!

)
Cheers
Finales I Didn' Like:
Seinfeld
other finales just weren't that memorable. I have no opinion of them.
