Nolan has made some of the dreariest films in recent memory, but this incomprehensible nonsense takes the cake. While keeping a straight face, actors deliver lines such as "dreams within dreams is too unstable" and "if we get killed we'll be lost in limbo till our brains turn into scrambled egg." DiCaprio and company supply the ham. This movie tells us that ten hours of real time is equivalent to one week of dream time. That explains why this nightmare of a movie feels like it goes on for two days despite the running time of two and a half hours. And if one falls asleep while watching, the only way to resume one's normal life is to limbo under a totem pole.
