Warehouse 13 is a little darker than Eureka

Warehouse 13 is a little darker than Eureka, but they are companion series, with crossovers. (I'm a couple seasons behind on both. sadface)

Wild Wild West seemed like a good recommendation. I would never miss an ep in the original run. Wonder how its steampunk secret agent fun stands up for the modern Battlestarwars kids' tastes, though.

Then for another old series that inspired a lot of us, there's the Avengers. Mrs Peel! http://bit.ly/JsCxwj
