It's the Simsons, in a PG theater setting, and they're taking advantage of that fact. I don't really need to say any more.

Okay, so just a bit more.

It's funny, with nothing held sacred, and will never be shown on broadcast network TV uncut (Homer giving the finger, the parts of that naked-Bart skateboard scene you'll never see in a trailer, and cussing). Even a lower-third banner advertizing some supposed Fox show ("...yes, we'll even advertise duirng a movie now."). The plot? Well, there is one but that doesn't really matter. This is Simpsons off the wall, well aware of the TV-induced limitations they no longer have to deal with (like, actually using Schwartzeneggar's name for their strong man-action hero character). See it in a theater, or later in DVD if you must, but just make sure you see it complete and uncut.

Oh yeah, sit through the end credits. There's a bunch of stuff in there (naturally).
