Warehouse 13's Debut Is A Ratings Win, But Can It Beat Eureka?

The first episode of storehouse-of-weirdness show Warehouse 13 was the top-rated cable show of the night, with 3.5 million viewers. That doesn't beat Eureka's 4.1 million debut.

It's also not clear whether Warehouse can beat Eureka's third-season average of 3 million viewers per week. Meanwhile, how will Eureka do in its new doghouse slot of Friday nights? And why aren't both these shows airing on Tuesday? [THR]
