They clearly learned from their past mistakes
I don't recall any mistakes, all I know is that the finale of the first series polarised the fanbase (I was in the "like it" camp).
I'm watching episode 4 of RESURRECTION right now and it's sort of like listening to Modern Talking's
Back For Good album that was produced 11 years after their split-up in 1987.
The only reason for that reunion album was to get more of the same and it was kind of disappointing to get exactly that, and at the same time it was disappointing that the sound was a little different and therefore not as good as the originals.
Damned if you do, damned if you don't, and damned if you try - that's the Modern Talking Syndrome.
I loved Dexter NEW BLOOD because it filled the gap in Dexter's life and then it showed us "what happened next" including the dramatic return of Dexter's son Harrison.
In RESURRECTION, everything and everybody has moved to New York and the first thing to notice is that there's no sense of place, which is an ironic thing to say about one of the most cinematic cities in the world.
It's just that the Miami Police Department (and Iron Lake in the sequel) felt like communities that
belonged to Dexter, and his nightly boat trips to get rid of the bodies added a lot of atmosphere to the episodes.
DEXTER was always two things:
1. to build a case against the serial killer and then deal with it
2. to be a step ahead of his Miami Police colleagues and pull the wool over their eyes while he was doing his own thing (this was always super-unbelievable because the only way to achieve all that was to be awake 24/7, but I didn't care).
So, New York Dexter starts with a boring serial killer (which has already been taken care of), Angel Batista on his trail which is kinda old hat considering everything that's already happened (including his guest role in New Blood) and Harrison's trouble with the police because he killed a drug-date-rapist.
Harrison believes his father is dead and that's why Dexter doesn't reach out to him. As it happened to Debra Morgan, Dexter tries to manipulate Harrison's life in a positive way and make sure he won't get hurt. He's there to
protect his son and they won't let you forget it because he mentions it every five minutes.
All in all, I'm not very impressed with the current goings-on but maybe the Serial Killer Club is going to change that.
Soaps, mafia stories and even sci-fi series have that natural, never-ending theme about them, but DEXTER has always been a novelty and maybe that's why it looks so tired and dated now. And yet, and yet...I couldn't resist.
