Best:
Boy Meets World. Touching and heartwarming, and a good way to sum up the series. What every series finale should be like.
Whos the Boss? was also great, EXTRMELEY sad though.

Its a great episode, though
Worst:
Full House. Didnt even sum up the series, just an episode about Michelle falling off her horse. Maybe it would work as a season finale, but NOT a series finale. Facts of Life was dreadful, too. It basically wa sjust the pilot of the spin-off that never happened.
