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.

2/5

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

“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]

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

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

A really weak season, but still interesting. The storyline is very good, the pacing is excellent, and it has a great villain and ending. Although it has some logical flaws, it’s still a great prequel. 7/10.

I’m surprised it didn’t get a higher score. The soundtrack was amazing for acting is fantastic. Beautiful camera works set design costumes, just perfect. A breakfast fresh air really. So hard to have a awesome new show. There is nothing like this on TV and Paramount had to kill it.
