It's a Japanese live action movie based on surviving dangerous games. It's available in Netflix.
The Story: It's really simple story. Students have to play some games and the loosers will die. It has some plot holes but overall it's good. Some questions left unanswered.
The Music: It's nice, not that bad or not that good.
The Performance: Acting was also good. Not extraordinary but they were good.
The Message: I think the message was be yourself and have good in heart and kami (God) will help you at the right moment.
Note: it's only my thoughts and yours can be different and that's fine.
