Believe Me is a movie difficult to categorize. On one hand it appears to be a faith based film while on the other it seems to be a satire of the Christian community. Straddling both genres makes it ineffective in both.
In that sense, along with impressive special effects, Chronicle succeeds in keeping its story firmly planted in the real world despite its science-fiction premise. It's likely that not all outcasts would use newfound abilities to defend the weak, save the planet, and become a hero.
