Jaz, what do you have against john ryhs davies? anyone who was an original 'slider' is automatically forgiven any bad movie choices and or bad acting period, in my book that is.
i never really caught more than an episode of season 4 or 5, but last year me and my wife watched seasons 1-3 and she loved most of them. i'd only seen about half myself. by the way season 4 is finally coming out on dvd in march, though i'll probably wait for 5 to come out before watching it...
Season 4 and 5 weren't that great. That's when their budget got slashed, they couldn't afford JRD (or he quit), and they moved to Scifi. I think it was one of Scifi's first productions that they actually paid and so they were on the same set week after week and had to explain it.
