First of all, I have no idea who is giving this film 1-star reviews. I assume it's being done by people who either don't like Tim Tebow or by people who can't stand Christian culture, because there is absolutely no way that any fair critic would give this movie anything close to a 1-star review.
That said, this is one of the better Christian films that I've seen. Several Christian films I've seen are what I tend to call "too cheesy" or the ending was "too happy". (I'm not a fan of everything always working out in the end -- I don't think that's realistic).
Anyway, my standards for Christian films tend to be pretty low, but at least this one had a somewhat realistic ending and I didn't find myself rolling my eyeballs during scenes, which I sometimes do.
As a male, I could relate to the emotions of two of the film's more disgruntled characters, which I appreciated. As a sports-themed film with several male characters, I thought this film would be more appealing to men -- but so far, females have rated it higher on IMDB than males have... so what do I know?
If I were a secular person watching this film, I might rate it a six or a seven out of ten. As a Christian, I'd probably give it an eight or a nine. (I gave it a nine because the 1-star reviews are obviously bogus and need to be compensated for).
For what it's worth, I thought Passion of the Christ was the best Christian film I've seen. (It didn't have much of a plot, but it was well done). The second best I've seen is "What If..." with Kevin Sorbo... and Run the Race probably takes the #3 spot. Not perfect, but pretty well done -- especially for a Christian film. Enjoy.
