I watched the first episode of this through gritted teeth, for its existence renders a fair old chunk of the conclusion of the book I'm working on absolutely fucking redundant. I spent a lot of time rehearsing the particulars of Luka Magnotta's deranged bid for immortality and now I'm going to have to delete near the whole fucking lot, for I didn't say very much that isn't said in a more immediate and more arresting way in this. I can keep some of it, the most important bits, the stuff about the videos themselves, but there's still a good 4500 words that are now for nothing but the bin.
Anyway that aside I thought the first episode was really good. I dunno how original its approach is. The bits where they just filmed people watching or not watching the videos reminded me of Grizzly Man, and other bits reminded me a lot of Catfish - the film, not the series - and even that 3 part BBC documentary about paedophiles. But it's undoubtedly well put together, and I was captivated for the duration even though I knew the ins and outs of the case. Still had me gripped.
I'm not sure that it wasn't having its icepick and eating it a bit, far as the footage itself goes. It seemed to derive a bit too much pleasure from taking you right up to the edge of the unwatchable, teasing you with what it might show or it might not. A sadistic sort of bent to it, at times.
But, I'm going to watch the last two episodes tonight, see what else I have to delete over the head of the fucking thing.
Also, I'll second the Hail Satan? recommendation above. One of my favourite films of the year. I wanted to join them immediately after watching it but there's no chapter around here, had to make do with signing up for a weekly email. Which isn't quite the same, somehow.
