Manos, Mitchell, Time (I forget the second word in the title: Chasers, Spliters, Warpers... something like that) are all great.
I thought the Joel to Mike switch was handled well, even though I'm more partial to Joel than Mike (nothing against Mike, I love him too.) Didn't like the woman as the evil scientist.
I literally (and I mean literally) have every single episode of the show, and am working my way through it. The very first access cable shows are tough to watch because the production value is so low, but its interesting to see where this amazing series got its start.
