Oh, Sleepy Hollow didn't learn anything from anyone, JMO, including the writer's room götterdämmerung of season 2.
My UO on Marlowe is that his skill is selling high-concept ideas to studios and not writing or characters or plot. I think it's not a coincidence that everything started going to hell in season 3 after René Echevarria left.
Echevarria was responsible for ST:DS9, a show which had a ton of completed ships between competent, powerful adults who respected each other. Marlowe's output is Die Hard on a plane and two movies where a woman being threatened with rape was just part of some guy's power struggle. Echevarria went on to produce Teen Wolf, Marlowe gave weekly interviews (sometimes with his wife) about what a soul-destroying erection killer being in a relationship with a woman is.
I also don't think it's a coincidence that the pilot Marlowe wrote had to be rewritten, recast and reshot to get the show we eventually got.
