Awful, contrived, silly, overbaked, shrill and in the end pointless. Colossal waste of talent from actors who are capable of so much more. Norton plays two characters here neither believable. Nelson, Sarandon, Lynsky and Russell wander through the picture looking like they have no idea what they're doing in the picture or while we're bothering to watch it.
What's interesting about American reactions (professional and amateur) to Norton's recent projects (this and Stone also) are claims that their plots didn't "make sense". (A similar opinion was expressed in a Times article for Stone). Those estimations miss the point. These two films are character studies, charged with philosophical content--low, I concede, but seemingly still too much for the average US viewer.
My entire review is found here: http://niklasblog.com/?p=5004 -- I liked this film about two twin brothers, played by Edward Norton. They're very different: one grows pot in his Oklahoma home and the other wants to attain more and more academic prowess. The first concocts hare-brained get rich schemes while the other drinks tea with scholars and speaks - when he has to - about his "eccentric" family.
