I was bought In The Loop as a leaving present from work.
My only criticism is that it's too like the office, i don't like the cringe-worthy humiliation humour that's all the rage for the last few years.
The bits in the film i didn't like were Tucker getting out played. Malcolm Tucker is the man, and no-one else should upstage him or take the piss and get away with it.
Otherwise, class. I laughed out loud. a lot
