To make this movie funny they have used all the cheap tricks they can, swearing, drugs, sex, poo and so on. You get the picture.
Now, cheap use of these tricks will easily ruin a movie or make it some kind of cult classic. Except for some unjust swearing Death at a funeral does integrate these things pretty well and most of the time you don’t even notice.
Because it’s really funny, but also cleverly done. Excellent actors , scripting and cutting leads to: fun. Even the poo scene is so well done you do not well uneasy as you often would do.
One to watch.
