With Rogen, along with James Franco, Jonah Hill, Jay Baruchel, Danny McBride, Emma Watson, Rihanna, Mindy Kaling, Michael Cera and others all playing themselves -- or at least their perception of how Hollywood and the public view them and their personas -- the film also comes off as a big inside joke as mixed with a "Scary Movie" style spoof of disaster and horror films, complete with an extended sequence lifted from and inspired by a film that was made before many of those involved were born, "The Exorcist."
In some ways this is just a creepier, slightly funnier horror-pic spoof than anything in the recently resurrected “Scary Movie” franchise; along with its references to “Rosemary’s Baby” and “The Exorcist,” the film spends a considerable amount of time elucidating prophecies in the book of Revelation, often with an impressively straight face.
If you like dick jokes, urine jokes, the "Scary Movie" series and Danny McBride turning his usual brand of sociopathic humor up to 11, this might be the movie for you.
Even worse, Rogen and Goldberg give up almost immediately once the crap hits the fan, killing off three-quarters of the cast as a lazy, throwaway afterthought and then sending the survivors indoors for a patience-testing, claustrophobic chamber piece that makes light of rape, includes the kicking-around of a severed head, and tosses in a demonic possession subplot for no reason other than to show how much better, believe it or not, the spoofing of an exorcism was done in 2001's " Scary Movie 2 ."None of the cast, save for perhaps the butt-kicking, ax-swinging Emma Watson (2012's " The Perks of Being a Wallflower ") in a cute but too-small part, take themselves seriously, and that is the true death knell of comedy.
