I wish he was cast as Grindelwald instead. Colin wasn't over the top with the acting and yes he was menacing because he was basically Grindelwald but maybe Graves wasn't really a bad person. Grindelwald is also good with dark magic so to be able to be Graves is quite impressive but I'm sure Graves put up a fight with him before Grindelwald finally got him. I would really love a backstory on Graves.
