Dexter: Original Sin Is Bringing Back A Key Part Of The Original Show
New Blood Didn’t Include One Crucial Ingredient
For the most part, the reviews forDexter: New Bloodwere positive from critics. That limited series, which takes place years after the divisiveDexterseason 8 finale, sees Hall’s character living in Iron Lake, New York, under a new identity. After being outed as a serial killer in the original show, the character no longer works as a blood spatter analyst, but as a clerk in a sporting goods store.
Dexter: New Bloodsports a 77% critics score and 74% audience score onRotten Tomatoeswhile the original series has a 71% and 81%, respectively.

While the evolving story necessitated Dexter’s change in profession,his job as a crime scene analyst was a crucial part of the original series. Dexter’s day job gave him the means to identify and hunt down other serial killers, and his actual investigative work made up a large portion of the series. His job at Miami Metro also, of course, upped the stakes since he’s carrying out his own murders right under the noses of otherDextercharacterswho work in law enforcement.
All 6 Dexter Characters Confirmed To Return In Dexter: Original Sin

It remains to be seen whetherDexter: Original Sinwill be able to recapture the magic of the first few seasons of the original show, but Gellar’s casting is a promising development.
