That's why they really don't need to keep making these "uplifting" sports underdog movies over and over. They have some great films already, and instead of being inspirational, these new films come off manipulative, formulaic, and in the case of "The Blind Side" insulting and unintentionally racist. I swear, Sandra Bullock got a pity Oscar for that one.
That said, I swear I read somewhere that the real life person the antagonist of Rudy didn't mind that they tweaked the truth, especially in reality he couldn't have been more supportive.
And also, when it comes to sports underdog movies, I kinda have a bias due to my favorite sports film, where the underdog actually loses. Yep. Rocky. Freakin' love that movie. And the Third one where they got Jim Henson to redub Kermit. Stopped watching the fourth one when the cartoonish robot popped up.
