Pretty damn good
First, to those who are offended by this: GET A CLUE!!!
There is no such place as French-land or Canadialand or whatever in real life. This movie isn't about putting people down. It would have been just as amusing and no more right or wrong if it was the "Americanians" invading from some *PLANET* (yes, they come from a PLANET, not Canada, idiots). It's sad that a movie that's actually fairly entertaining is given poor scores just because people are wrongly offended. Sure, I know you have to put up with idiots and 5 year-olds on this site but it sucks anyway.
As for the movie: you already know the graphics aren't going to be eye-popping. Despite that, there is a lot going on and things are animated well and fun to watch. Sound and music are ok. Violence is as expected. Humor is decent. And you have a scene selection (which is absolutely necessary for a movie of this length) so that's perfect. I would have rated this a 9 overall but I gave it a 10 to try to help balance out the votes from people who don't know any better.
