I went to see this yesterday in the cinema with mixed feelings. I don't háte Jim Carrey, but most of his movies make me walk away half-way through. Sometimes he just gets too over the top annoying to a point where I can't take it anymore. But there's always a lot of laughing to be had. But Yes-man surprised me in a positive way. I really laughed a lot and Carrey seems to have found a middle way in doing some really crazy stuff without being over the top annoying.
There's the occasional pulling of strange faces and of making strange noises, but not too much, just right. Me and my brother walked out of the cinema with a feeling that we'll be yes-men, when we want to.
All in all a great movie!
*no trailer added because youtube decided to be down and out atm.
