The amount of plot contrivances and absurd coincidences were brutal I thought. Intensely lazy writing on what was meant to be a final love letter to the fans.

It borderlines on so bad it's good for me. Angela's reaction to a ton of corpses on display is laughably bad. The entire series of events that enables her to discover Dexter's secret is so incredibly stupid. Random characters disappear or have their motivation outright change on a dime. Almost none of it makes sense.
