I feel a prequel would be boring because you already know the outcome... But a spinoff could go so many different ways that can keep you at the edge of your seat
A prequel series would be more intersting. Sort of like "Hannibal Rising" which focused on Hannibal
Lector's early years leading up to who and what he is today. A spinoff would have to star a really
interesting character to hold the audience interest. "Deb" played by Jennifer Carpenter is the only
character in my opinion who would be interesting enough to pull it off. The other characters in
Dexter, although good as backround characters are not interesting or dynamic enough for a spinoff.
