On another note – the movie is pretty decent. If you are an fan of the regular FOX animated show then you’ll be pleased to get more of the same in a feature film format for this movie.
The major difference I noted is that The Simpsons Movie makes use of the CG effects used for Futurama instead of the purely hand-drawn format typical of the Simpsons TV animation.
Overall I’d give it a 4 out of 5 because 3 is too mean and 5 is too good. It’s “pretty okay”. 🙂
