Shinobi

[Drunk Monk]

Romeo and Juliet as ninjas - super ninjas actually with magic powers like poison kisses and tentacle sleeves. Lots of CGI flying weapons and flying about. A five-on-five duel between ninja clans. Amusing sword fights, but most of the swordplay was reduced to a look of shock at seeing a katana blade jutting out from your stomach because you've just been stabbed in the back. It's ninjas after all.

Amusing but not quite over the top enough to be a DOOM flick.
