SPOILERS about the SLIDERS cast...
Jerry and Charlie both left after Season 4, Sabrina did come back for one episode in Season 5. Cleavant tried to keep the story going with the new cast but it wasn't the same story any more... Same premise, same time, same place, different worlds, wrong cast...
I liked Sliders until mid-season 3 when FOX kept moving it around and lost viewers. I did stick with it until the end of Season 5 on SciFi channel though. I kept hoping for a return to the original story line. I've always been a huge "what if" fan. Sliders was a perfect idea that never really got utilized properly on tv.
now for the topical stuff...
I miss V, but it got sillier after the mini-series ended and the budget dropped for the series.
Anyone remember the series about an island in the Bermuda triangle where people of several time periods co-existed? It was an NBC show, I think.
