It's sounds interesting with the concept, but the execution is poorly done. There's barely any story other than the main character trying to figure out how to escape from the locked up asylum with a Madman inside. It does have a decent build-up with the madman introduction and how deadly he is. But most of the movie is just the characters trying to escape while surviving against the villain. The movie has a pacing issue with the suspenseful scenes happening too quickly to have tension in it and is predictable to guess what happened next. Also, there's not that much happened in the movie to make it interesting or enjoyable to watch throughout because it's mostly just the same things. The characters try to find ways to escape or fight back, but it ends up being a failure. The climax itself isn't that bad because it's somewhat suspenseful, but the characters don't make the best decisions.
