Good god, Dexter is excrutiatingly bad. It was never a great show, but there's the show is completely adrift with only two episodes left of the series.
If there's anymore proof that the producers have just been dialing it in for many seasons now, this is it. It's somewhat excusable when it's a cash cow and they have to maintain a status quo, but they can do whatever they want know but they don't because no one even gives a shit at this point.
