I've seen every episode except for the last 5. I had to stop.
So you missed Harrison's treadmill-fail? No!!!
It needs to be seen. It's a microcosm of what Scott Buck did to the series.
I realize this is a minority opinion but Season 6 and 7 had some great stuff in it.
Like Batista saying "tableau" in 6? I really enjoyed Stevenson in 7. It was as if Dexter did in fact face the Punisher. That was exciting stuff. Then the vacuum that's Hannah McKay became a major player, and the series never recovered.
One thing I like that the writers did (a rare clever thing in Season 8 ), was we didn't see his Dark Passenger in the final episode and we didn't get any narration in the final scene. To me that definitively means he stopped killing.
Nah, I'm guessing Moloch finally absorbed Dexter. I'm just kidding, but if you're unfamiliar w/ the reference, check to see what Lindsay introduced in Dexter in the Dark. It's mortifying.
I still have very fond memories of the show but the final season was so, so, so horrible. There isn't anyway I can defend any of it.
