If not a 10 out of 10, it's a 9½! Best movie I've watched in a while. Director Hisayasu Satõ was firing on all cylinders. The cast was excellent. Yes, it's a low budget pink film but you'd never notice.
First, ignore the standard movie description which is not accurate. Basically, a man has lost his memory after being attacked with a baseball bat. Other people also were attacked with a baseball bat on other occasions. A nurse and doctor are looking after him. That's all I'll give away as learning the rest is the enjoyment of the movie. Everything unfolds with each character having their own story and eventually everything connects together. Brilliant script.
This is a pink film so has the obligatory sex scenes. Lead actress Maya Shiraki is also naked quite a bit. She is stunningly beautiful (I really want to know what she looks like 35 years later!) so why not? She only seems to have made four films (2 I can't locate) but wish she made more.
I rated this movie 10 out of 10. Honestly, a difficult decision with a pink film, low budget and only a few actors. But I enjoyed it so much I felt I had to. If someone wants to watch their first pink film, this is one to watch. I definitely recommend it.
