After watching a string of lackluster disappointments, this was a breath of fresh air, though not great by any means, just a movie that got under my skin and stayed in mind since; felt very true to the high-school experience and the camaraderie amongst the teens was natural, reminiscent of stuff like The Dangerous Lives of Altar Boys. What really got me was the performance by Ross Lynch. Never heard of him but he give a helluva committed turn as the titular character. My Friend Dahmer is essentially a disturbing character study that manages to shed a little light on the most depraved serial killer to have ever serially killed.
What was interesting was how disturbing I found it despite the lack of brutality or heavy violence, it's always this potential that doesn't quite materialize but we know is teetering below the surface.
