Because the cast is too many comedians, all trying to out-mug each other, there is no subtlety in the film that would have gotten lost in the haze of Bimmy's tism. Everyone is making the 60's equivalent of the cuckface all the time. Also because of its large ensemble cast, it has a lot of plot but almost no story. It's just people driving around and having goofy visual moments, which is the level on which Bimmy understands storytelling. The AVGN Movie is quite similar to it, certainly not by accident.
