World's Greatest Dad

I don't understand how this can be called a comedy. This is a depressing movie with a depressing begining, a depressing middle and a depressing ending.

This movie is a portrait of a pathetic loser, who fails at his passion, at raising his son and at the only good thing in his life, the relationship to his beautiful teacher collegue. There is no irony, no playfulness, no dark humor, just misery. It's about as funny as watching a car crash. How this is supposed to be funny? I don't know.

As a drama it works pretty well though. If it would have been advertised as that, i might have liked it. The saving grace for me was the great performances, especially the always amazing Robin Williams.
