This movie was an exceptional end to what has been a great franchise. Although animated, it had depth, heart, and humor. You cannot go wrong with spending your money on this one. But don't bother with the 3D. In my opinion, it was a "nice-to-have" but not a "have-to-have". It did not add or detract anything from the movie.
This was one of the best horror movies that I've seen in quite a while. Not only was it scary where many movies are just mindlessly gory, but it had some legitimately funny moments that didn't detract at all from the serious "scary factor" of the movie. This will be one for the DVD collection.
