who knows, its entertainment, Rev Billy has been around for several years. He used to be on the US club circuit, and I heard him on radio promoting his shows for several years. I imagine that "act" has run its path and he is hoping for bigger things. Is he SINCERE, and does the movie have a message, have to see it to say. Reverend Billy's act I have heard is not high brow humor.
However, imo a waste of money is not necessarily so. It might be, for you, but it might have a message that gets thru to someone in the audience, and they will change. That benefit could far outweigh their ticket price.

Movie demographics in the US have a very young audience.

There is some irony, but I "consumed" this film last night and am heartened to find I now have the definitive answer to the mush of December, the most depressing time of the year for those of us who don't buy or pray our way into the anxiety-ridden apex coming up on the 25th of next month. "It's a Wonderful Life" not.

There isn't much most xmess seasons than could make me guffaw the way "What Would Jesus Buy" did. I wrote the good reverend this morning suggesting they at least put the lyrics to their new versions of "Joy to the World" and "Deck the Halls" up somewhere. They went caroling in suburbia last year and sang these. The homes they visited all seemed to be tremendously enjoying the songs. If I had a better singing voice, I'd consider doing it myself.

There is of course, some irony in consuming what you have to to with your computer to visit The Oil Drum. If it is counterpoint to dominant culture, this film is too.
