This is a pointless waste of time. I cannot understand the characters actions and reactions, the plot is flawed, plus the script is painfully slow and that is an absolute kill joy in a thriller. Do not watch this movie except if you have problems falling asleep, this might actually do the trick. I do appreciate Richard E. Grant‚(TM)s efforts to make the story believable but at the end the whole of the film is senseless and quite boring, after the first few minutes you do not longer care about the voices or the hospital, or any of the characters. It all has all an impression of a group of actors that got together at somebody‚(TM)s shabby flat and decided to make a movie over the weekend. Very disappointing.
