This was very dark at times; some truly horrible crimes and I'm surprised at the 'Teen' rating really.
Gripping story, good mix of characters, decent acting.
Lots of shouting though and a few really (like really, really) dumb moves, which spoilt it, sadly. The script writing isn't great (some very amateur dialogue), although the story idea is pretty good.
I have to mention a favourite actor (you'll know if you watch it) in one of the best serial killer portrayals I've ever seen, which definitely makes it worth watching.
