I need help identifying a movie i watched between 2004-2007, so it came out probably early 2000s. I remember the main character being dead(I think a zombie) but it wasn’t a zombie movie, more like a coming of age, some light comedy. he was living on a bus in an empty mall parking lot I think. young male, I think there was a love interest or a friendship but a lot of internal dialogue as he’s explaining to us about being dead and not wanting to be. I’ve searched everything and can’t figure it out.
