Just finished Orange is the New Black, I'm really impressed. No letdown episodes, numerous rich, interesting characters.
Minor "general direction" spoiler:
Some slightly more detailed thoughts:
Lastly, this is my first experience with the Netflix model. I don't like this "dump a whole season out there at once" idea. A good enough show will earn my time, and if a show is good enough half the fun is finding other people who like it to discuss each episode with. Releasing it like this really limits a lot of that, and I think it limits the amount of buzz and acclaim a show can get.
