A buddist afterlife, is that why unpopular?
Afterall, Brooks goes to an afterlife full of levels of rewards and questions and no particular punishment. The worst possible punishment is heading back to Earth. Even the porn guy isn't in any particular torment for his "sins". Perhaps why it didn't receivethe publicity or interest from the general public in the U.S.? Afterall it's fairly blasphemous, ain't it?
I think the film is charming, but wonder if the satire would've been funnier if Brooks had gone further. ie) Murderers in a trailer park, watching EVERY DAY of their life, feasting on fast food?
One does not sell the land on which people walk
