Dexter is only 20, so will Original Sin have about 10 seasons?
Dexter is 20 in "Dexter Original Sin", which takes place in 1993.
The first season of "Dexter" takes place in 2006, so that means Original Sin can have a maximum of 13 seasons!
And I noticed IMDb listed "Dexter New Blood" as a "TV Mini Series", whereas "Dexter Original Sin" is called a "TV Series", and "Dexter Resurrection" is also called a "TV Series".
So "Dexter Original Sin" will have multiple seasons (maybe 10 seasons or 13 seasons), and "Dexter Resurrection" should have several seasons (anyone's guess), because I think the writers will be too scared to kill him off (plus they have no idea how to anyway), after the threatening backlash those writers faced in 2013 and 2022!
And the thing to remember about Dexter, is that he's supposed to be smarter and more disciplined than all the other serial killers.
So it makes no sense for him to be caught.
Remember there was a real life serial killer named Samuel Little, and he confessed to killing 93 people (60 of them confirmed by the FBI) between 1970 and 2005.
So Dexter's killing career should last at least 35 years (which would make him 55-years-old, and that would be in 2028), and maybe a lot longer, because he's probably smarter than Samuel Little.
