My honest impression is that it is too difficult to understand.

It uses CG to recreate the dream world, but I don't understand what's going on, and it's too long because of the promised gunfights.

I think people who like it will like it.

The director is the same person who produced "Interstellar", so those who understand it will understand it, and those who don't will not understand it.

I could tell that Ken Watanabe was putting his body on the line.
