McTiernan is trying to get at some sense of heroism in the final battle (think "Braveheart" without the inspirational feel), but it feels strangely unaffecting, mostly because the scene is like several of the earlier battles, totally incoherent.
So, reluctantly, Ibn falls in with this band long-haired, hard-drinking, broadsword-swinging brawlers -- who seem to be a cross between Klingons and Mel Gibson's "Braveheart" clan.
Quake with fear (or boredom) at first sight of the Villians of our Braveheart-flavored tale, the actual Eaters Of The, Well, You Know.
By trying to make a poor man's "Braveheart" instead of a middlebrow "Seven Samurai," McTiernan has turned the otherwise automatically lively Banderas into merely a dull but earnest adventurer.
