So I'm almost done with Parks and Rec. Season 3 (will have to check Season 4 online or something) and so far I can say that I love the show. I actually enjoy every character. Ron Swanson might be one of the best characters but Aziz really makes the show hilarious, as well as Amy.
I do like Rob Lowe and Adam Scott's addition to the show but I feel that Adam Scott's character in Party Down was so much better and I am sort of upset that he left there to go to Parks and Rec.
Ron starts getting much more developed/time devoted to him in the last couple of seasons- he's my favorite character on television, I think April is pretty funny too
