Warehouse 13 was pretty good.
From what I understand the cancellation of BSG wasn't syfy's(screw you, forget you) call. NBC/Universal wanted to pull the plug and so they did. That's all there is to it. Caprica wasn't doing well enough for a second season, and Blood and Chrome was given a purposely stuffty timeslot.
Eureka was cool, don't know why they cancelled it. They also cut their monday night weaboo hour, which also really confused the hell out of me.
