I laughed so much during this film that I literally thought I was having some sort of heart attack. The rest of the audience seemed similarly amused. It's cruel, tragic, sympathetic, racist and Islamophobic, and all the better for all those things.
You kind of root for the heroes. Even though they're all morons. A bit like Inspector Clouseau, they live in a world where not everyone is an idiot, but they somehow make it through.
I wonder if it will be funny in ten years time? Slapstick and political humour date very quickly.
