Seems interesting. Serial killer movies/tv-shows often are. Working on such a theme is like walking on a thin wire, I think, though. A little mistake and audience would leave with a bad memory.
What make this movie different than other movies on the same topic.
The profile of the victims and how the killer's motivations for acting are gradually discovered. The personality of the police investigating the case is also peculiar.
I searched it a little on the net and found that it recieved some awards too, and that the performances are also top-noth. I am definitely going to watch it. Thanks for the recommendation.
