Lonergan is simply brilliant. The way he combines real life drama with literary references by that showing his characters inclination to intellectually interpret dramatic events and their gut reaction to them, is just incredible. This is by far the best movie of 2011 and the fact that is wasn't even nominated for an Oscar shows just how flawed the Hollywood promotion machine is.
I've seen quite a lot of reactions from viewers that leave me mystified: Lisa's a spoiled brat, no more of Paquin's screaming, the film takes forever blabla.... I have a suggestion for you : go see Spiderman or some action movie that will keep you satisfied in terms of pace because you certainly didn't get anything out of this movie. It has nothing to do with how likable Lisa is. This is a coming of age movie. And yeah even spoiled upper class brats go through it and its always dramatic. Anna captures it superbly. I haven't seen such compelling writing for a female lead in quite a while.
