We've mostly been watching TV series with Net Flix. I never watch TV because of the commercials...so it's perfect in that regard.
So far we've watched the entire series of "Lost" & "Battlestar Gallactica". Currently we're in like the 4th season of "Heroes"...and I'd recommend all three of them.
Regular movies, they have pretty much all of them. Thing is you can't stream most of the ones you'd really want, but you can get the disc.
The good thing is they have plenty of B grade Zombie movies online.
