This is stellar noir crime. What starts as the usual serial killer flick becomes soon an intense and very gripping masterpiece. The story evolves in small steps and what looks like loose ends are ultimately cleverly connected. There are many twists and turns but not for the pure sake of it but it just reminds you to never believe what u see on the 1st glance. There is way more in 13C. besides to figure out who is the killer. It really makes u think and questions pop up the likes of ... what if he's right ? You will see the abyss in people's mind & behavior and this will leave u sometimes speechless. All actors do a great job and I also liked the setting and light - it supports the twilight zone atmosphere. If you're up for something real and are done with high polished and sleek massmarket tv crime I can highly recommend this superb crime/drama! The only reason I left 1 star off was the very last scene which I found personally a bit bland compared to the overall greatness of the show.
