C Me Dance/YMMV

Designated Villain: Satan. Sure, he's the devil and all, but he doesn't do much that affects the plot. He is just there to jerk Sheri around a little bit and then gets called a loser.
Fridge Horror: B-movie reviewer Scott Foy explains in his review that Sheri's ability to instantly convert people means they aren't making a choice to follow Christ -- she's using "supernatural Mind Control". It's a case of the heroes out to conquer The Evils of Free Will.
