I loved it. :D
From the previews I got the impression that it was going to be a lot more slapstick (not that it wasn't slapstick in parts), but once I got past the expectation I thought it was bloody brilliant.
Did a really good job of making the protagonists sympathetic without supporting their actions too, I think. I really felt for Waj and Omar by the end of the movie, and I thought the bit with Omar's brother was a really subtle way of showing what kind of prejudiced attitudes lead to shit like this in the first place without being condescending about it...
