Il canone del male

The film takes a lot of time to build the main character, but it is told in a vague way and does not show the unique features of the killer.

The student character cast is not deep, perhaps because of the lack of time, if it was made into a series, it would probably be better.

The end of the movie is really crazy, even though it's weird and some of the student character scenes are a bit goofy, but this is a murder movie lol.

But if you consider it as a regular murder movie, it still deserves a high rating.
