The group of main characters is pretty formulaic - we have the beauty, the thinker, the rich guy, the arrogant guy etc. - and so is the setting, a big locked mansion. The victims died in a locked room. A simple setup that is a classic in the investigation genre for a reason. After that, a riveting story unfolds. With fresh twists that will surprise even long-time fans of the genre. There is also slight comedy which will make you laugh without throwing off the suspense and mystery.

The actors did a great work embodying these characters so they feel like individuals rather than stereotypes. Special mentions Yin Zheng and Zhang Ben Yu. Yin Zheng lives up to every expectation I had for him in this movie, it is a delight to watch him act (if you are also considering watching this movie because of him you will not be disappointed). Now Zhang Ben Yu, I have never seen him before this movie, and I am very impressed - he brings all the mystery and wit his character needs to constantly keep you on your toes, well done!

The music works well and doesn't take away from the movie, but it isn't particularly memorable either.
