if I were to be super nitpicky, you have to suspend disbelief between some celebrities making cameos as fictional characters and others showing up as themselves
also it had way more serious themes than classic black comedies we came up on (Friday, Coming To America etc.) so at times the comedy was over the top for the audience to remember they're supposed to laugh
there are some really unexpected scenes, meaning the novelty probably will be gone with no reason to watch it a third time
but it's well done and I wasnt expecting to be so pleased
