We loved “Fireproof” as well as “Flywheel” and “Facing the Giants”. Sure, some of the supporting actors are amateurs, but they are entertaining and redeeming movies rather than culturally destructive. It’s fun to watch all these movies and see the different people show up later as different characters. Also, look for the Jay Austin Motors (from Flywheel) license plates in the two later movies.

Also noticed a sign for Bobby Joe Duke's Lollipop Shop somewhere around the middle of Fireproof.
