The animation would have been pretty amazing 15 years ago, but by today's standards it looks like this film was made by a bunch of 3rd year animation students. The plot is full of basic tropes and any attempt at humor was lost on my entire family. My 6 year old laughed once at the very end at a dog in a mailbox. The writing and cinematography fall flat. The script includes a lot of bullying in the form of physical and verbal abuse, and the overall "doggie prison" theme may be a bit dark for younger kids. There are lots of poop and pee jokes, as well as name calling.
At no point during that hour and a half did I feel any emotion other than boredom.
