Occasionally, you find a show that takes a while to find its groove, like Scrubs. The Millers seems to think it has found it from the start. The talented cast seems ready and willing to dive headfirst into the roles with abandon, herein lies the big problem.
Almost everything here is so overblown that it is almost reaches farce level. Kinda like watching Scrubs, sans the whimsy, and the charm and the clever banter and smart humor and the likable characters. If the 1980 cult turd Flash Gordon was to be serialized, it would be and apt comparison to the tone of this mess.
Lets be honest, when Will Arnett is the actor showing the most restraint you either have a horrible idea or have no directorial control over the cast. Director Kevin Smith once mused that he was not strong enough to control Ben Affleck during the making if Dogma. The Millers leave you with similar feelings.
