Not only is this movie unoriginal and superficial at its very core, but also its logic is flawed and it is not really a good kids movie.
There are far too many prototypes: the not-so good team coached by a washed-up ex-minor league player, the "evil" coach who has won a string of championships that wants to "rule" the baseball league with another title, the "heart-broken" kid who wants to win for Dad, the mom who wants the best for her little boy, the rise and fall of the "lovable loser" type team, etc. It seems to all be a bunch of one-dimensional and predictable characters that begin to work each and every baseball cliché.
I agree with the reviewer, Brett, who mentioned the flawed logic of this movie. It's hard to exactly know what the message of this movie is. Do the parents want their team to win? Do they want their kids to practice, not to practice? Why do they want them to quit a game that is a passion just because some coach tells them they aren't good enough? The naivety of this movie excels all baseball movies I've seen. Couldn't they put a little more thought into some of these characters?
The slight positive to this movie were the few chuckles that were there. Ed Asner does a decent job as the ex-minor league player turned coach, and has a few good lines:
"Baseball is spelled F-U-N-D-A-M-E-N-T-L-E" ..
"Can you spell irritating, kid?"
However, overall, the lines and the action aren't fun, but rather superficial, and it's ending left me, well, confused (kind of like they just said, "Let's stop the movie right here."). A movie that could have been much more, but failed miserably.
Even if it is just suppose to be a fun movie, Perfect Game doesn't even come across as a true kids movie. I would suggest that if you want a kid's movie with a little more spirit, rent "The Rookie" instead. If you are wanting a good baseball movie period, see "The Natural" or "Field of Dreams."
