Brutality...
I only caught a couple of scenes of this movie, when it was on tv, but from what I saw it did a pretty good job of its depiction of Bundy's perversions and overall insanity. I came in during the scene when he bludgens the two sleeping girls to death in their dorm room. The blood and gore looked pretty cheesy, but the actor's portrayal of allowing himself to be overtaken by his thirst for carnality and over all indulgence in the animalistic depravity of his actions was very effective. That, coupled with the icy tone of delirium that the music created, was pretty damn disturbing; and I'm not easily vexed. I like to think I have a pretty good understanding of human nature and I thought it was one of the most viscerally convincing takes on what I've always imagined the nature of Bundy's perversion driven debauchery to be... Just saying.
