Did anybody catch the line Ben said to Jack (I think) about the other random passengers in the tail section? I'm paraphrasing:
Jack: "What's going to happen to all those people back there?" Ben: "Who cares?"
At first I thought it was just Ben being a cold bastard but after a second I started laughing, seeing the tongue-in-cheek reference to how we barely learned a single thing about the Oceanic 815 Tailies.
Bang on. The last four seasons had the odd bright spot but were mostly just a slog to get through. Dexter was unrecognisable as a character by the end and not in a good believable-character-arcy sort of a way.
