So, lets take, for example, Terra Nova, and the BBC show Outcasts.
Both sound cool, Terra nova is about some humans who time traveled to like 65M BC to survive on a clean earth. Yet the episodes are not about surviving a harsh alien environment, etc.
its human on human conflit.
I dunno why the change - Tho I imagine it is so they can show more crap wrestling :P but the SCI FI channel is now called SY FY.
Looks like they are going to have some new/interesting stuff. Warehouse 13 (Had a lot of neat steam punk gadgets) was pretty good and Stargate Universe looks promising.
