Dexter as a whole remains one of the finest original series Showtime has ever produced. However, the last few seasons left a lot to be desired, and it's unfortunate this final season does little to change course.
I won't spoil anything, but my biggest criticism of this season was that too many loose ends weren't addressed and longtime characters did not receive proper send-offs with new characters, twists and subplots being introduced and rushed.
The audio and picture quality of the Blu-Ray set is very good, and this is worth adding to the collection for collectors and fans who have been with the show since the start. However, I find very little replay value.
