I saw this movie on TV while waking up in the middle of the night, and I was lucky because this movie feels like a dream. Everything is done so that you could feel as lost as the main character, you start wondering why and how. Sometimes the movie can make think of "Misery" (1990/inspired by the Stephen king's book) but unfortunately it's not as deep and strong as misery is, the story of "coma" is somewhat predictable and unsurprising but the movie is still very entertaining. I'm very harsh when it comes to giving a score because I think an "OK" movie deserve a 5 or a 6 (on a scale of 10) and not a 7 or 8, so I will give this one 5/10; it's not the best movie in the world but it's an interesting one.
