Alive

If one is seeking a movie with atmosphere and plenty of gore, buckets of blood and many sinister scenes, this checks off all the boxes. In the opening scene, a bloody and heavily bandaged man, manages to get off the table, crawl down the hall, is discovered, and later wakes up across from a woman who is also bandaged, and there is a man (doctor?) supposedly trying to make them better. But it seems to be in a very dilapidated hospital, with lots of blood on the walls and floor, and instruments which seem more for torture than healing. The two are not given names, but try to form an alliance to escape. The man helping them seems sincere, but there is also an element that puts his role in more of a malevolent form. As they try to escape, they find things that are more and more disturbing. So if this is your type of movie, you will find it quite passable. And you will probably not expect the ending.
