Reviewing period weapons and methods of using those weapons; good idea.
Discussing the mindsets and cultures that created the "Warriors" themselves; good idea.
Everything else about this show; Bad idea.
My biggest hangup is the "my dad is going to beat up your dad" bullshit that goes back and forth on screen. While I'm convinced that it's all just part of the show (I refuse to think the experts they bring in for demonstrations are really so childish...), but it still reminds me of watching the UFC after Lesner got involved.
My other big issue is context; Gladiators fought in arenas, Ninjas worked in teams, etc, etc, and pitting one against another in a neutral setting proves nothing.
But it did make me think of another, older, show that was in a similar vein and fun to watch; Conquest. Anyone else remember that one?
