Perfect for 10 (ish) yr old boys
I took my son to see this. He loved it. It was gross and he laughed a lot. This movie is exactly what it's supposed to be and nothing more. I gave it a 10.
P.S. I also appreciated that, while having a good message, it wasn't "preachy." Rare thing in kids movies these days.
