As I love both Halloween AND cartoons, I had high expectations for this movie. I left feeling a little disappointed.
I'd only seen a couple of previews, and hadn't looked up the cast, but pretty early on I realized that the voice of Dracula was totally Adam Sandler, and then I couldn't stop HEARING/SEEING Adam Sandler. It ended up being distracting, and sometimes obnoxious.
That being said, this movie had cute moments, and several laugh-out-loud funny ones, but it still relied far too much on fart jokes (seriously, within the first 5 minutes!) Apparently kids these days aren't savvy and still love fart jokes. I put this cartoon solidly in the middle of the pack. I was mostly entertained and didn't hate it, but it had the potential to be so much better.
