As another review said, it's quite rare such experiments on the rather rear end of the movie spectrum) get produced, so thumbs up (not literally up theirs) for this, also as the (brave) actors are really good (I mean come on, how on earth would you prepare for such characters/roles?) Generally more hilarious and entertaining than gross I found; also the impro street scenes with members of the public presumably not knowing what's going on are quite funny.. All in all an interesting mix of many genres. And even involving a summoned Bowel-Demon - lol.
