If you loved the show, you will love this! It's just so funny! The plot was pretty cool too. I also love how Numbah 3 was to be Grim's replacement. I always knew she was evil. My only complaint is that it felt annoyingly long at times, longer than it should have been, and that's saying something as it really wasn't that long. All in all, it's a great film for Billy and Mandy fans, but if you're not a fan of the show, you may wanna skip this title.
