This week was about coming back to earth, and coming to terms with the show's strengths and weaknesses. Gotham is a far cry from a great drama, but it has decent building blocks that could one day get it to that echelon.
The main plot, then, was a deftly crafted Gotham procedural with a memorable baddie and a sense of macabre fun... but there was so much more to savour as well.
"The Fearsome Dr. Crane" was clever, creepy, funny on purpose, deliberately disturbing (instead of thoughtlessly so), and graced with an excellent villain-of-the-week.
The bottom-line result is that Gotham has evolved into a more consistently engaging show, even if some of its conventions might eventually get a bit repetitive
There's not much in the way of his family history or how Dr. Jonathan Crane came to take on the terrifying [Scarecrow] mantle. With the character's introduction on Gotham, that will finally be made clear.
You can not keep doing this, Gotham! You can not keep taking all the names of super villains we know, swapping out the first name and saying it's their cousin!
