Shows like Warehouse 13
et cetera are not light and fluffy-- they're just not dark and gritty. They are all very solid, well-written, well-produced and well-cast shows that seldom fail to entertain. They're certainly a far cry better than the "rated M for Mature" stuff that is currently considered "edgy."
Glad to see someone else here who enjoys those shows as much as I do.
There's a few of us out here.
