I finished it late last night. It's probably my favorite Telltale series to date, and I've enjoyed it a bit more than TWD. My only real complaint about the series is really that it's gotten so far away from an adventure game format at this point; it was always been light on the puzzle elements, but now it mostly feels like a choose your own adventure visual novel on rails with some QTEs thrown in. The first episode had a few neat, if mostly inconsequential, investigation moments, but it felt like the series focused on conversations and fights after the second episode.
Still, the story was well-done, the plot points were mostly tied up nicely and the climatic confrontation was engaging (as were most of the fights in the series). It's interesting that as I got more invested in playing as Bigby, I felt less ambiguous about letting him cut loose during fights (to the degree that the game would actually let me.) I still refrained from having him go lethal when possible, though.
I have to admit that I was kind of confused by the meaning of the final conversation with Nerissa at the end of the story. Was it implied that she was actually a glamoured version of Faith that Bigby met in the opening scenes of Episode 1? Also, I'm surprised that the game mostly forgot about Crane. Last we heard, he was supposed to be on a plane to Paris, but as he was mostly a liability, I wouldn't be surprised if the Crooked Man had Bloody Mary get rid of him. .
