Critics Consensus

Original Sin cares less about injecting fresh blood than reviving a tried-and-true formula, making for a prequel that's just solid enough to scratch the Dexter itch with a scalpel.

New York Magazine/Vulture

The resolutions themselves, however, are mostly clunky, reflecting the overall clumsiness of the season.

Rated: 2/5

“Dexter: Original Sin” isn’t unwatchable. It’s filled with entertaining performances, but the story feels like it’s beating a dead horse, rather than offering up an exciting prequel that has a compelling reason to exist.

Turns out there’s still blood -- just a few drops -- to be squeezed from everyone’s favourite vigilante serial killer.

...a solid and absorbing crime series whose biggest crime is that it's a prequel.[Full review in Spanish]

JoBlo's Movie Network

The fact that this series has flashbacks is even more ridiculous than the hair Patrick Gibson sports in the first episode.

Rated: 6/10

Dexter's tale is quickly becoming the most overtold origin story after Batman.

NOOOOOOOOOO! I'm so upset this was canceled, it is soooo good. I don't understand why we can't have both (original sin and resurrection)? 😭😭😭 here's to hoping they will change their mind.

WOW! Can’t believe how good this show is. I’ve watched Dexter 3-4 times, and this Original Sin has the capacity to live up to the hype. Characters are spot on. Killed it!!

I’ve tried a few times to watch this show but it’s just not good. So glad resurrection was created and is replacing this one.
