Unfunny does not go far enough - clearly a lot of money and talent was thrown at this - but it is pathetic. I went in with hopes but after 20 minutes I was wishing I was tired and could take a nap.
Sadly the overacting and repeated shouting kept me awake for most of it - but I heard no laughter from the audience. It might appeal to some 8yr olds but the rude humour typical of Ferrell puts it at a higher certificate. A real stinker of a film.
