I had some other complaints after watching MI3 but this is more of an issue with the genre than with this movie. The best action films (Witness) can transcend the genre, but we aren't really looking for that, are we? We just want a shot of adrenaline to the heart.
What bothers me most in a movie like MI3 is the completely inhuman emotional reactions that people have to intense, life-threatening situations. I will post a few examples below.
