Eastbound and Down is dumb, and it plays it up. I finished two and a half seasons and may yet finish the last season and a half. It's easy to watch and entertaining. It lives and dies on its writing, which varies wildly from episode to episode.
Danny McBride as Kenny Powers is amazing. The womanizing and fast living gets a little old at times, but I'm amazed at how they manage to keep it fresh, even though it's essentially a one-joke show. The worst parts of the show are when McBride isn't driving the scene, such as when Will Ferrell's car infuriatingly boring recurring character comes back on.
