Query: Uniquely terrible

The guy killing birds with his singing was the only good thing about this movie. And even then, after a while it wasn't funny anymore, because they played the card way too long. It is almost insulting just how bad this movie is. They don't even have accurate pack dynamics, they just pulled it all out of their butts and expected us not to notice. The writing started weak and ended weak, the voice acting was mediocre at best, and I could swear watching this movie gave me temporary cancer. Don't waste your money or your time on this travesty. The combination of poor storytelling and random toilet humor make this is the worst animated film since Eight Crazy Nights. I want my On Demand money back!
