Bad acting
The movie was painful to watch in the opening.
It might be the illustration of the writer's egoism and personal void, I suppose. The character himself admits that his own life is boring and uninteresting. I don't find the dialogs very interesting, nor funny until the romance begins. (nobody laughed in the theater)
But the scene in the stairs between the two men is played badly, in my opinion. The words are badly delivered, and the moves are wrong.
