Génesis: En la mente del asesino

Interestingly, there are no comments on the series at all :) I love Spanish TV series, detectives especially, it's strange that I haven't seen this series anywhere in the lists before.
First impressions. The series is from 2006, but the shooting looks like it was shot in the 90s. Otherwise, it's not bad. Quite an interesting plot of the first series, art, attempts to figure out the killer, is a good start if you put up with an outdated picture.

But this series was good. Not such obvious criminals.

It seems to be in a series of blunders. Marcos kills the father of his childhood friend. He runs back to his hiding place.. throws the gun there, goes out somehow closes the door behind him? If he was kept locked up, how did he even get out? If the door was open for some reason, then why did he close the basement behind him and how did he know how it even opened? And even moved a shelf?

Some kind of implausible plot. The pious boy from the orphanage is just a killing machine. So many people killed in broad daylight and didn't get burned. Figured out who was doing what quickly, invisibly penetrated everywhere. How did he get into Mateo's house - it's not clear at all, what was the guard there for? In general, the series is generally average, Mateo's performance in this episode is too theatrical. I'll watch the rest, because I don't like to quit TV shows, even though it's not a fountain.

Some strange teacher in the victim's apartment, finds a postcard from the killer and touches it without gloves. It is clear that he had to be careful, but suddenly there would still be fingerprints
