You're looking for social commentary in a movie called THE HANGOVER?
Bob, you should just preface your reviews with a note saying:
"Yes, this is one of THOSE movies--the ones I personally don't like so if you go see it and enjoy it, I will label you an idiot and blame you for bad movies."
OR
"I liked this movie, so it's either a surefire hit anyway (superhero movies), some foreign film that most people will gloss over ('cause they're idiots), or a movie that's going to bomb at the box office because stupid people (like you) don't appreciate things like I do."
