Never have I seen a movie where so many people grab a dagger by the blade. Come on guys. It's a dagger.
I also will admit, I don't understand the premise of the dagger itself... If the gods were so pissed off at humanity for the egregious amount of violence they were prone to, why, of all things, did they give them a symbolic KNIFE. That seems pretty violent. Why not the Small Toy Elephant of Time, or the Lovely Hair Pin of Time. It just had to be an item that could invoke more violence, huh? Bastards.
