My Friend Dahmer.
Very well done. I'm not sure how accurate it is (based on my 10 minutes of research, it seems to be pretty accurate, though I never read the book from which it's based) but having just finished it, I have to say, it's left a sort of sad, hollow pit inside of me. We see many of the factors that helped to create the young man who became known as a monster. It did leave out certain aspects of his life as a very young child but nevertheless, we get a (in this case, sad) sense for how each and every experience and facet of our lives can help mold who we become. Most of the time, we evolve into fairly insignificant creatures, going on with our daily lives. We eat, we work, we sleep. But through Dahmer's seemingly inherent affinity toward bones (which seems to stem from an incident with his father when he was very young that came before the film's timeline begins), his father's education and job which helped "guide" Dahmer to become more curious and hands-on in dealing with carcasses and bones, his parents' tumultuous relationship, his own blossoming sexual identity crisis as a teenager when life can be very confusing, especially as one as odd as he seemed to be, all while being a bad alcoholic starting somewhere around the age of 14, and we got a serial killer.
What we did not see, from the little I read, was how little time his parents seemed to spend on him and how little true love he received, especially at a younger age, before the film starts. Basically his mom was a nutjob and mess and the dad, when not at school or work, tended to her. Nevertheless, the film is very well done and it's interesting to reflect on how the infamous man we know just wasn't some "sick ****." It's easy to label but life is far more complex than that.
