Hey, there are worse reasons to make a movie than the hope that a kid and a few professional ballplayers might be able to change the world. Is Alex English a fantastic actor? No... but he's believable. And if you are willing to suspend your disbelief about the plot, you can have an amazing ride with this movie. It's a great idea... and the movie plays it off pretty darned well.
Nothing wrong with a movie that make you believe that a dream could happen.
