Much of the output of H.P. Lovecraft dealt with the worlds hidden beyond the veil of the senses – whether in higher dimensions or in the kingdoms built by men's dreams. In those realms dwelt unfathomably ancient beings whose malevolence was far outside the understanding of humanity.
John Dies at the End posits that these beings are really just massive jerks.
Something like Lovecraft for the slacker set, John Dies at the End is a tongue-in-cheek horror comedy that leaps between worlds (and the worlds between worlds) with gleeful abandon. The film features swarm intelligences that speak like wannabe gangsters, a carnivorous mustache, a meat golem, and a living drug that unleashes its users from the moorings of time and space. Though the movie's climax doesn't live up to everything leading up to it, up to that point it's one heck of a ride.
