His scenes and overall performance felt like such an incredibly calculated effort to get people to like him again that I didn't find his scenes funny at all.
I would like to see him make one move, say one word or date one woman that didn't feel like it had been setup buy a group of PR professionals. He really assumes he can fool people - and by the sounds of the laughter in the audience at the screening of Tropic Thunder I attended - I guess he can.
