alot of the shows mentioned are very good.
I reccomend Dollhouse (great sci-fi series with 2 seasons and a proper ending)
and the 2 seasons of spartacus, its not a documentary but an action serie based on the story of spartacus. Its one of the bloodiest and raw series ive seen aired on TV, so if you dont live alone i would reccomend locking the door because of the brutal nature of the show.
