Ones I liked:
90210: Like OTW said, it all had to end with Donna and David getting married.
Mad About You: I know that it takes place in the future, but hey, it's good to know how everyone turned out.
Who's The Boss?: Loved the final scene........
Tony and Angela FOREVER
Ones I didn't like:
Full House, Growing Pains, Fresh Prince et al: Moving away...nice way to end things-LOL
Felicity: I liked the show a lot, but it could have done without the final four episodes.
