Good watch, could watch again, and can recommend.
This is a surprisingly charming story with a positive message.
Sure, it's a "dirt humor" movie, but the cast works really well together, and it minimizes the amount of baseball in a baseball movie without removing too much.
While it does do a lot of things that are either too stupid or potentially offensive to be funny, it does even more that are legitimately funny or have a positive message to them.
Ultimately, if you like Rob Schneider, David Spade, or Jon Heder, then you'll probably like this, because you'll get a lot of them.
I'm not sure if I can recommend this as a good baseball movie because i'm not a fan of baseball, but it manages to be there without being overwhelming.
