I think most of the secondary characters are the best part of the show.. the primary actors like Biggs, Prepon, and Schilling? I could do without them.
It's getting some good ratings at Rotten Tomatoes and Metacritic so most people like this season as well.
Not sure if you're aware of this site but I check it every morning for any new streaming titles, Netflix doesn't do a good job of it but this site does - http://instantwatcher.com/titles/visual
First day or so of the month is when they get the most new ones in.
