Sci-Fi has its problems... I'm no fan of Ghost Hunters (aka farce hunters?) or its spinoffs, or any of those destination truth shows....
However, they helped pioneer the way for original cable TV programming, and single handedly reinvented the Friday Night Lineup (my family's name for it) way back with shows like First Wave, Invisible Man, Farscape, and today I wouldn't be happy without Battlestar Gallactica, Dr. Who, Eureka, Stargate Atlantis, The Dresden Files, which are all still in production. There are probably more I've overlooked.
For the original TV programming alone, Sci-Fi has redeemed itself.
THC and TLC have.... well... there's mythbusters.... and... um.... HOW many shows do they have about ships fishing now? Wait, scratch that question. Man vs. Wild has some great survival tips if you accept it's scripted.
So overall THC/TLC has a lot to make up for lately

EDIT: P.S. Who saw the 360 show? Any good?
