I really think people just didn't understand this film. SPOILERS
I really think many missed what this film was about, as well as those that are defending them. It's a cerebral film as well as one without a happy ending. These are two things many people do not like at least here in america. Watching a lot of foreign films shows that much of the time you don't get the prince and princess riding off into the sunset.
So many think it's going to be a horror film in the sense of things jumping out at you and startling you...this movie is a subtle one. The horror is in thinking 'What if...'.
Also many people think all the events were 'real' or worst really miss the boat and think it's all just random. What had happened up until the point George goes into surgery was all 100% real time. His family had alluded to the fact that George always lived his life 'safe', never taking chances and had a lot of phobias.
Prior to his surgery he had an interaction with each of the other characters that would later manifest itself once George ends up in a vegetative state due to complications having a colonoscopy (perforated bowel).
During his 'time' in this state the fears he had on his birthday (unneeded medical procedures, medical exorcism, the 'white' man vs 'black' man, racism in general (giving his doubletake of the foreign doctor), not taking chances with life, his wife's fidelity, wondering if his daughter was into girls rather than guys, his friends lives, hospitals/attorney's really wanting to prolong their clients misery for profit, etc), manifest themselves into what he thinks is the real world.
George really believes he is trapped in a hospital where malpractice runs rampant. He believes his wife has already moved on with his doctor (and perhaps is behind his problems) and when he finally can reach out to his attorney, the guy wants to delay things and keep him there. His reassurance is it's already worth millions.
Other fears/desires come to play as well...he finds out his daughter is a lesbian (or at least bi), his son becomes an 'evil doctor', he has an affair, he journeys into uncharted territories/doesn't play by the rules.
I thought it was a good movie. The movie was never released to be a blockbuster, but the actors do a decent job given the constraints they were all probably working with.
