That's My Bush is no Brak Show Starring Brak but it's still a pretty ruthless and relatively subtle satire of sitcom conventions, though the last episode is a little more obvious about it. It's a bit of a one-joke premise and so it is often more "oh that was a clever reference" than laugh-out-loud funny. But there are moments. Unfortunately a few too many of those laughs come from jokes from the sitcom formula - which are just more risque than they otherwise would have been - rather than the satire of the sitcom formula. It makes sense to me that this failed. I think it's a little too close to home for most American TV audiences.
