[Beanamir of Gondor]

I'm not sure which one was better. With the stupid Grishnakh you got the stupid Merry and Pippin, who sort of float along with whatever happens, and are mainly the comic relief during the moments when Gimli fails. But, then, with the smart Grishnakh, you get to see Pippin saying "gollum, gollum", and actually being useful instead of just another curly mullet with a cute accent beneath. All in all, though the Grishnakh-getting-squashed-by-Treebeard was pretty cool, I would have to go with the Ring-driven Grishnakh. Then he's evil all around--evil to the hobbits because he wants the Ring, and evil to the other orcs because he's betraying them to get it for his own glory.
