see no point of the powerful armour- spoilers

The armour, which is supposed to the whole crux of the conflict, isn't that powerful at all.

He defeated the moonking just by his 3 string guitar thing. So, I don't know why the moonking was even afraid of hanzou finding the armour, in the first place.

I guess, this was discussed earlier, I'm just late to the party, cos' i just saw the movie.

All in all, pretty good movie for me. just nagging details.
