Right, he's a guy who bonds with animals more than other human beings. I just wish we'd gotten greater insight as to why that is and how it's affected his life up to this point. His symbiotic with the creatures gets him out of plenty of scraps, to be sure, and he has an innate trust in animals - but what about humans specifically bug him too much? Isn't he a little similar to Grindelwald in some of his overarching ideas? I have faith future films will address this in more detail.
Eddie Redmayne played the character as autistic. Yes, he meets DSM-V criteria as far as I could observe. Which bothered me.
It bothers me because that was clearly not how JK Rowling wrote the role and he ultimately came off too flat and lacked personality.
As a character, if he had been written as autistic, it could have been a fantastically interesting narrative point. From an improper social interaction at Hogwarts that lead to his expulsion, his obsession with animals to perhaps a deeper understanding of magic suppression as he himself could have very struggled with repetitive behaviours as a magical child. That would add an interesting extra layer of danger to his underlying power and psyche. It would have made him far more compelling and worked well with the story points of this movie that I won't delve into. It would have made his character a social advocate and could have given a very progressive story writer another misunderstood minority to champion.
But JK Rowling didn't write that, which is totally fine. Instead, Eddie Redmayne played the role that way anyways, which I didn't connect with as a result. He played the Danish Girl again.
The story was fairly good and certainly original, but I could ditch the director and the leads going forward.
It's kind of the opposite problem of The Force Awakens, which had a great director and fantastic leads that I connected with. The story was much more reductive.
In the end I'm more excited to return to the Star Wars movie Universe than the Potter one, and I'm a far bigger Potter-head. The side-kicks not-withstanding. But the leads were throwaways in Fantastic Beasts.
