Manny Coto took over? That's depressing news. If he's doing to Dexter what he did to Enterprise, cancel Dexter now. (Yes I know that Coto's lack of success is somehow still invisible to the majority of the bbs.)
Manny Coto isn't the showrunner. That would be Chip Johannessen, who also had a short run as the showrunner of MOONLIGHT before it was cancelled. Both are refugees from the cancelled 24 (where Howard Gordon was the showrunner).
EDIT: I should have flipped to the next page. Jack Bauer
beat me to it.
