The danger of obsession should be completely obvious to anyone. I mean, if you combine deep-rooted insecurity with some sort of magical object that will make you instantly cool come on! You're just asking for trouble! So, of course, when poor Arnie Cunningham sees a way to boost his negative charisma, it soon becomes the central focal point of, well, everything. In the process, Arnie loses his best friend, a gorgeous high school hottie and eventually, his life because of his obsessive fixation on the 1958 Plymouth Fury that initially captivated his attentions and seemed like a way to instant popular status. Yeah, obsession is bad.
