Dexter, stuck in a living hell, with the urge to kill constantly gnawing at him as far from paradise as you can get without it being a frozen fucking tundra.
But that was never the intention of the writers. (Which you could be excused for not realizing since they wrote a very confusing, stupid ending to the original show.) The point, they basically said, was that Dexter
needs sequels can't bring himself to commit suicide because he's a psychopath, and psychos don't do that, so instead he moved somewhere in the Midwest (
later retconned as northern New York) like a lot of serial killers do and for the same reasons: to avoid the eyes of the law, and to have the option to kill without being caught.
EDIT: Never mind, I'm an idiot as proven below.
The thing that got me about New Blood was that moving to New York State seemed way too risky for Dexter. If he'd taken off for Alaska or the Yukon, that makes more sense, especially the Yukon, as Canada won't extradite anyone who would face the death penalty and that would be a safeguard for dexter if anyone ever found him. I guess the writers just aren't that smart.
It's not that they're stupid. It's that they wrote themselves into a corner with the ending of the original series, and they didn't have the integrity (or perhaps creativity) to stick with the original intention. If the job is "write a sequel story to Dexter," how the fuck do they do that? Well, they might just have to fudge some details. (Which they are doing noticeably on Resurrection, too.)
I hate nothing more than a retcon. Have some integrity, stick to the established "facts," and write your way out of it.
EDIT: Fuck me, if you watch the original scene you can see a New York emblem on a truck. That was always the plan
Maybe the thinking was Dexter wanted the remote living but also the option to escape to Canada if he needed to.
Or maybe it's like I imagined the Walking Dead writer's room, where 8 of the 10 writers are smart and 2 of them are stupid as fuck, but they're friends with the showrunner and can't be fired.
