"Fireproof" is about a couple on the brink of divorce working back to real love and respect for one another. It is explicitly evangelical and a little clunky. But its heart is in the right place. It gets Southern evangelical culture right (it is set in Albany, GA). I particularly liked the parallel complaints that husband and wife made to their friends about how the spouse was the real problem because he/she did not give the complainant enough respect.
"Fireproof" has been the talk of the pro-marriage circuit this year because it shows in some detail what steps and what changes a couple who want to save their marriage can take to get on the right track. And the happy ending teared me up, even if it was a little cheesy.
