Hmm, we recently got a Wii, so I've been on a Netflix binge now that I can watch it on our TV.
If you haven't seen Kick-Ass, that's a great place to start. I also just watched Apocalypto and was pleasantly surprised. If you like horror or 80s action, Netflix has pretty good quality - Terminator, Die Hard, anything with Kurt Russell or Sylvester Stallone.
For shows, the League is good and I just started and enjoy Party Down.
I've also been in the mood to watch stuff that requires no attention or work at all while I get drunk: Deep Blue Sea, Killer Klowns from Outer Space, Little Big League, Leprechaun in the Hood, Ed, etc.
And if you've never seen Swingers, get on that ASAP.
