If you’re going to commit to a blasphemous stoner comedy mocking the New Testament prophesy of the coming Rapture, you’d better go all in. Because halfway isn’t funny. And either way, you’re going to Hell. At least in the eyes of some.

Thus, the failed deadpan comedy “Rapture-Palooza” pairs up a seriously unflappable Anna Kendrick and John Francis Daley as survivors on Earth, not taken by The Rapture, trying to fend off the amorous advances of The Anti-Christ played by Craig Robinson. And it isn’t as funny as it sounds.

Sure, taking the Bible literally (“Did anyone think this THROUGH?”) in regard to the Apocalypse can seem awfully silly in the age of computer generated effects. The righteous are “sucked up into heaven” in a flash — empty bowling shoes are all that’s Left Behind…in the bowling alley. Where’s Kirk Cameron to explain all this?

Thus are the poor sinners still on Earth — Lindsay (Kendrick), her Dad (John Michael Higgins, reaching and swearing for laughs), her Mom (Ana Gasteyer screaming “Why why WHY?”), a church-goer taken by the Rapture and then sent back for getting in a fight in heaven and Lindsay’s stoner brother (Calum Worthy) — left to cope with plagues of trash-talking locusts, foul-mouthed crows, rains of blood (“Gross!”), angelic wraiths who like the Weed and “fiery rocks from the sky,” all preparations for the return of Jesus on a white horse for the Day of Judgement.

The Anti-Christ is probably the only black politician in the history of Idaho, a guy who seizes power and proceeds to nuke cities that don’t fawn over him — London, Chicago, Orlando…

“NOT Orlando! Think of all those ride operators!”

The post-Rapture infrastructure imagined by New Zealand director Paul Middleditch has a Seattle that is still operating, despite the rains of brimstone — TV stations still broadcast, people still buy sandwiches because “People appreciate a good sandwich, even when the world is ending.” It’s just a lot less crowded.

The germ of a funny idea is here, and this ambitious picture drew a better cast than your average “Scary Movie” installment. But it is seriously slow, as if everybody involved had second thoughts pretty much every day they were on the job.

And if cast and crew are the praying sort — not likely — they’re feverishly hoping “Rapture Palooza” will disappear faster than a righteous bowler when The End is Here.
