I had no expectations for this series when I started watching it. In fact, the only reason I checked it out in the first place was Dick Casa...err, I mean Ryan Hansen, who was awesome in Veronica Mars. And I was delighted to discover that there are much more VM related people involved with this show, starting with creater Rob Thomas and ending with the occasional guest star like Jason Dohring or Alona Tal. But is just fanservice for VM fans? No, this show definitely stands on its own.
Party Down is one of these modern comedies with the occasional drama, a style pretty much started by The Office. I don't really care for these kind of shows usually, but the humour here works quite brilliantly. The jokes pretty much keep coming at you with rapid fire, and most of them work; if you don't get one, don't worry, the next one is coming right up. If you judge comedy series by purely how much they make you laugh, Party Down deserves a high score. The jokes vary from pop culture references to dirty jokes, from physical comedy to witty word plays.
The first season is pretty solid and funny, but I found the second one lacking at times. Having said that, I watched all the 20 episodes in two days, so it never really went too much downhill.
Party Down is nothing special, but it is definitely worth checking out.
