I'm halfway through Dahmer, and I have to say I'm thoroughly enjoying it.
I'm a couple of episodes in and am currently undecided. I remember being fascinated by it as it unfolded on the news while I was on a childhood holiday in Germany, but am not sure I appreciate a dramatisation or see this as legitimate / constructive rather than simply trivialising it in pursuit of profit.
Certainly makes for very uncomfortable viewing given how utterly horrific the subject matter is.
