Nowhere near as good as the first, yet I find it pretty entertaining. The humorous and dramatic bits are not balanced very well (ex. when it cuts to the house fire right after a very hilarious moment) and a lot of the dark moments just feel extremely forced. I personally think the movie should have stuck to a more humorous tone. Great supporting cast, though, despite the movie's flaws.
The main reason to watch this film, in my opinion, is Ashcan & Pete - Jon Polito and Adam Goldberg sounded like they were having a blast voicing those two goofball dogs.
