Just finished watching How To Be A serial Killer and to be honest it was a disappointment. I'm pretty sure they got their inspiration from a Belgian movie C'est arrivé près de chez vous (Man Bites Dog,1992) from Rémy Belvaux, a movie that is by the way much better, I recommend you watch that one instead and find out for yourself. That said, How To Be A Serial Killer tries to be funny, dark humor (normally my favorite), but it's just not working. The acting wasn't great either, certainly not towards the end. Anyway, just watch the Belgian movie if you want good mockumentary on the same subject spiced up with some real effective dark humor.
