if it was weak in any area it was the story... but there was a fair amount of meta levels going on too.. like the whole script convos can really change the way you view the whole... as if he almost purposefully left huge holes or superfluous stuff in there (the whole selena gomez stuff went nowhere too).. maybe as an hommage to the whole trainwreck production style of B.. *shrugs* I don't know maybe a stretch.
I think it has to be about the details and there were too many to catch on any one viewing imo... like just identifying who the zombies are/were.. like who was the one dragging the guitar? nobody? somebody? Carol Kane was so perfectly and simply hilarious.. lol.
