About Abrams, yesterday I (tried) to watch again Mission Impossible 3 to study his directing and, screenplay aside (which, I HOPE, he had nothing to do with), here's my opinion:

-the way he put faces VERY CLOSE to the frame is painful to watch, making the resulting screen look cropped. I think he said they look more "intimate", but they just look bad compositions to me;

-I understand quickly switching between shots is useful to give a sense of tension, but during gunfights he completely abused of this "trick", making half of the time hard to tell what is really going on;

-to this, add "lens flares": they're so strong (especially in the helicopter scene), that basically cover almost half the screen, making hard to se what's going on (though Abrams recently said he is aware of this issue and he's going to use them less);

-camera shaking: common "trick" to make the scene look live and add tension. He shaked it half the times so much (even when unnecessary) that it kind of gives you headache (again, helicopter scene).

So, so far I dislike his directing. Later on, I turned up TV and watched "Killer Joe" which was directed by William Friedkin, and his work looks WAY more professional than Abrams's.
