I haven't read John Dies at the End by David Wong, although having seen John Dies at the End, the movie adapted from it by Don Coscarelli, I can only say it's become a priority, if only so I'll feel properly prepared to read the sequel, This Book Is Full of Spiders: Seriously, Dude, Don't Touch It.
One of the problems I have with movies these days is that all are made for an audience who has seen something like it. Everything is easily pitched to a studio with one of those "This meets that" comparisons that made popular in the public's imagination after The Player.
Is this a little like Drive-In by Joe R. Lansdale, which Coscarelli was at one time working to adapt into a movie, or maybe a touch like Fight Club by Chuck Palahniuk? Honestly, neither sounds right, but I'm not sure what I could do to get closer, at least without at also getting further away.
Is it like this trailer?
Again, it's something like that, but maybe more or, at least, different.
It takes something more than just originality to make something like this work, but it's still so refreshing to see.
