This is the perfect ending to a tv show that ended way too early. It is an psychological rollercoaster that you just want to watch over and over.
I already had my suspicions about whether or not everything so far in both the "real" world and the dream was one big elaborate dream, but i was thrown off by the evidence in the first episode (both psychiatrists came up with pretty sound evidence that their reality was real). Micheal Britten realization that there could be a 3th dream somehow jolted him out of the dream and he woke up with both his son and wife still alive.
I hate the fact that NBC cancelled this tv show. A tv show as this one so thought provoking and original comes along only a few times, while garbage as Jersey Shore is on their 5th season....
