This one feels like is could have been a filler episode in the first season, which is a big improvement over the last movie (the full feature). This movie at the very least has more depth than just people shooting each other. The movie begins with a woman named Izumi Yasaka, a latent criminal, arrives at the Tokyo police station and turns herself in while asking for help but she can hardly speak. Turns out she escaped from a special facility for latent criminals called "Sanctuary", where the public safety ministry has no authority and therefore reluctantly agrees to repatriate her, but it is obvious she'sterrorized by it. Inspector Shimotsuki and enforcers Ginoza and Kunizuka accompany her and inspect the facility. At first glance it seems to be a paradise compared to the regular correction facilities, but something about the behavior of the staff just doesn't feel right.
This movie is more of a thriller genre and less psychological so I wouldn't say it's as good as the first season of the TV anime, but is still well-made. It's also the first time in the franchise where inspector Tsunemori is not the main character (she does appear but not frequently), which will (unfortunately) be the case in the future as well.
Art and sound are just the same as the TV anime so I give the same score. Overall, nice thriller movie. Not the best I've seen but nonetheless not bad at all.
