In praise of boredom, at the movies and in life - Andrew O'Hehir, Movie Critic - Salon.com: What we have instead is the meta-boredom of a pop culture that's all bells and whistles all the time, and can't be switched off.
Thinking is boring, of course (all that silence), which is why so many industrially made movies work so hard to entertain you. If you’re entertained, or so the logic seems to be, you won't have the time and head space to think about how crummy, inane and familiar the movie looks, and how badly written, shoddily directed and indifferently acted it is.
