Just a really good movie

The Iron Giant.

If you haven't seen it, go rent it. It doesn't have much super-high-profile talent (unless you count Frasier's dad; and Harry Connick Jr, who's hot but not that high profile right now, car commercial aside; and I didn't even realize Jennifer Anniston was the mom until I just looked at the imdb site for the movie), and it doesn't have much in the way of fancy animation, but it's a great movie.

Simple plot, wonderfully executed, with a great ending. Go rent it. Now.
