[i]Hero[/i]is not a documentary.
It's an epic tale, grounded in history, but stylized and poetic. It incorporates elements of fantasy into an elliptical narrative, which includes several points of view presented as flashbacks, both real and imagined. There are cultural references that may be foreign to most western viewers. To be honest, I would love it even without subs.It's a visual treat!
