Why so much hype?

It's a mild crowd pleaser for people who are exhausted by blockbusters.

a film so unique, intoxicating and bizarre that it not only demands another viewing, but is also forgivable as a satirical comedy where the jokes eventually take the back seat.

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.
