The saving grace of John Dies at the End is undoubtedly its manic storytelling: the energy and pacing of scenes give the movie the impression of being told on the spot (which is of course what the framing device intends).

Gonzo freakiness in such doses that cult status is practically ensured.

I stopped taking notes when the woman disintegrated into a ball of writhing snakes.

I wouldn't count on the title giving you a leg up on the film's outcome.
