Edit: Many years later - I am keeping my original review, but I can no longer rate or endorse JKR's works, as I find her to be morally repugnant. 

OG review: I have been an enthusiastic fan of the Harry Potter series for over fifteen years. I loved this continuation of the world that was also a little more adult, aimed more toward an older audience (no child main cast, more nuanced villains and problems right off the bat). This screenplay was just as wonderful to read as the film was to watch. Initially I was disappointed that Eddie Redmayne was cast as Newt, as I was really hoping for Nathan Stewart-Jarrett, but he did not disappoint. He took the quirks JKR wrote for Newt and created a wonderful, multi-dimensional character. For all that he is the quintessential Hufflepuff, I found this simple direction:
NEWT
(lying)

to be the most subtle, yet true characterization of the adorable cinnamon bun that is Newt Scamander. Loyalty comes in all shapes and sizes, and if Newt has to lie his arse off to keep a promise to his (beast) friend, he will do it in a heartbeat.

The one thing I really wanted to find out through reading this was how the author intended the Graves and Credence interactions to play out. 

Graves stands outside, watching Credence intently. Credence spots him, hope flickering across his face. Utterly enthralled, Credence moves across the street toward Graves, barely looking where he's going-everything else is forgotten.

...

GRAVES
Shhhh. My boy, the sooner we find this child, the sooner you can put that pain in the past where it belongs.

Graves gently, almost seductively, moves his thumb across the cuts [on Credence's hands], healing them instantly.

Ferrell was directed to be incredibly creepy toward Credence (who, thank god, is supposed to be an adult - that was very unclear in the film). I'm glad the uneasiness I felt was intentional and not a product of my unfortunate mind.

Jacob's leaving scene has been made so much more impactful with the extra directions ("The pain is almost unbearable.") Crying in the library is allowed, right?
