Faith Based?

So, "Evan Almighty" opened much smaller than it needed to make up for its "most expensive comedy of all time" price of 200+ million dollars. The media watchers are surprised because it's a "family friendly" "faith-based" movie that is usually, so they imply, a sure thing to bring in the hayseed Christians and their kids.
Calling it faith-based is kinda like saying "King Kong" was based on a true story because there are people who have gone on trips and captured gorillas. Look, just cause you use the ark and a guy with a long beard doesn't make your movie faith-based anymore than an ex-VP showing a slide show in your movie makes it science based. And, believe it or not, there are some people smart enough to know the difference. Of course this is from a guy who hasn't seen the "Passion of the Christ" because I didn't think it could be as good as the book, so take this rant for what it's worth.
