If you're looking for hard-hitting political satire, save your money. Although it has actors playing George W. Bush, Laura Bush and Karl Rove, "That's My Bush" is not remotely about the real Bush administration.
Rather, the show is a parody of formulaic television. The premise is a standard family situation comedy about an ordinary doofus whose job just happens to be President of the United States. Tour groups walk through the living room during family fights. An obnoxious neighbor walks right in whenever he likes. The laugh track is one of the most important elements of the show, over-reacting to deliberately lame jokes and supplying dirty hoots whenever the president's dumb blonde secretary walks into a room. There's a tagline (clearly inspired by The Honeymooners) repeated at the end of every episode, with the "audience" joining in: "One of these days, I'm gonna punch you right in the face."
Each episode combines a serious topic with a timeworn TV situation: drug control and trouble with the mother-in-law, or missile defense and an illegal cable-TV hookup. Don't expect any light to be shed on the serious topics. It's all played for laughs.
If you're easily offended, save your money. There aren't many subjects Matt Stone and Trey Parker consider off-limits. The show isn't as scatological as South Park, but if you're prone to offense-taking, Stone and Parker are out to get you, and they're almost certainly going to succeed. If you can take it, there is some hilarious stuff here.
It's good there were only 8 episodes -- many more would have run the risk of turning it into one more goofy situation comedy.
Each episode includes an audio commentary track with Stone and Parker, and another commentary track with the entire regular cast. But, if you buy DVDs primarily for the "extras," save your money. Each commentary lasts only a few minutes at the beginning of the episode. There are no other extras.
If, in spite of all these warnings to save your money, you buy this anyway -- well, I think you'll enjoy it. I did.
