Don't knock it till we at least learn the plotline. Hopefully The Simpsons, like South Park before it, will make it well worth our effort to watch. Even if it just means we hear "rim job" being defined on screen.
Meanwhile ... Superman better not suck. I said this about Spider-Man and about Batman Begins and was pleased both times. Hopefully this movie will work, though I'm still pissed from a Smallville perspective at a minimum and skeptical about the cast.
