I'd forgotten how bad it had gotten towards the end of season 3
Recently started watching Sliders again because it's on netflix now, and now I remember why I stopped watching it towards the end of season 3 after the professor died. One reason being that they all started hating each other, wow so much infighting in a group of people that up to that point had had a "we're all in this together" attitude and had gotten so close. Then the professor, everyone's guru and the voice of reason, died and they added a very unlikable bitchy character in his place. And the story lines and special effects became lazy and cheap.
Anyway, that's my take on the whole thing.
