Yeah, and that's when they even do scifi at all. Like many networks, they don't do a whole lot for their namesake any more.
I was happy at first that they decided to guarantee Defiance 2 seasons, but after giving it an entire season to grab me, the show was just dull and uninspired, so I haven't watched it since.
I think Continuum is the best scifi show in a long time, so it's a shame that something of that caliber gets 3 and a half seasons, while the empty crap gets to last much longer.
