Anime!

Sometimes the line between fantasy and reality is very thin.

I have never seen a war re-enactment in person, but I imagine it must impose a striking sense of surreality watching men willingly re-enact such mind-bogglingly horrific events. Maybe in some twisted way it highlights that senselessness, and that's the point -- to make you realize the folly of it all.

On the other hand, maybe it's all just a bunch of hyper-violent macho cosplay.
