well look at the numbers that's not the case with F9/11.. Dodgeball was one of those.. but its been hanging in there with slowly declining returns... not a huge drop off... but the fact is, its a movie that preaches to the chior... its not going to move people who don't already agree with what it claims. The left will keep seeing it.. for a while, but it will have little impact.
Its a political propoganda hit piece, it will be forgotten.. it will never reach remotely the scale of Passion, which will be bought and viewed for generations.
More like the "rapture is here" to the mostly agnostic and atheist liberals as a corollary.
I bet you at least a third of the gross is repeat business.
