This finale felt pretty easy to me. I know Dexter in its latter seasons wasn't written as well as 1-4, but it felt so telegraphed that Dexter would meet his downfall. All his talk of being a phoenix that rises from the ashes, it being a new day- could you make it any more obvious that Dexter wasn't going to make it out of this?
The thing is that had Dexter not killed Logan, he might've had a compelling argument. Sure, the cameras were off, but he could say he told Angela the location of where Kurt kept those bodies. That wouldn't get the heat off of Dexter, yeah, and we've seen his mounting desperation, but him killing Logan and then calling Harrison from Logan's phone were rookie mistakes. Mistakes that Dexter of the past wouldn't make, but again, I get how desperate Dexter was.
It is weird to revisit Batista in this last episode, have him say that he's on the way, and then not see him show up. Not just for the possibility of a reunion with Dexter, but to see what he could contribute. Hell, maybe he'd drag Masuka along with him.
At the end of the day, Harrison being the one to put down Dexter does feel poetic in a way. I just the buildup to this moment was better handled because, again, it all felt so telegraphed.
