I've read several take-down pieces of the finale. One such review called in the "worst season finale in television history," which seems about right to me, at least among the shows I've watched.
What I'm really waiting for is the ultimately take-down piece about how, in light of the Holder revelation, nothing that we previously saw makes any sense. For example, the scene with Holder and the escort in the hotel room -- what the fuck was that? If he was in on it, why have that scene? And why the revelatory scene when he goes to the corner of whatever street, sees the Richmond campaign poster, and calls Linden? And why was he trying so hard to bust the teacher earlier in the season? I'm sure there's a laundry list of these questions that one could compile if one went back to watch previous episodes, which I'm obviously not going to do because this show sucked after episode 3. But, if I was so inclined, I feel confident I would conclude that NONE OF IT MAKES SENSE.
