Brilliantly Absurd I think that a lot of the bad reviews here are from people that are... well, slow.
The humor here is dry and quick. It's easy to miss if you're used to being hand-fed comedy or need a laugh track to tell you when something's funny. Think Hitchhikers Guide mixed with some Monty Python.
It's not often I actually laugh out loud at a show. This one has me doing that every episode. HBO has already renewed it for a 2nd season. Can't wait!!
