Sorry for posting this late; I was doing July 4 stuff yesterday, so I didn't have any time.
Warehouse 13 - Syfy, Tuesday, July 6, 9:00pm ET
The overuse of deus ex machina really bothered me last season, especially at the beginning of the season, but the show found its way towards the end of the season and ended on a very strong cliffhanger.
Eureka - Syfy, Friday, July 9, 9:00pm ET
Belatedly, I'm putting this here, because I think the show is way too wacky for its own good. Still, the show can be fun and there'll be a crossover with Warehouse 13 later this year.
Haven - Syfy, Friday, July 9, 10:00pm ET
After reading the description of the show, I was struck by how similar the premise was to Eureka. The differences only seem to lie in the tone of the show and the use of the paranormal instead of science. I guess we'll see exactly how similar is on Friday.
