7) Make Grindelwald An Interesting Villain
As revealed in a shocking third act twist (well, it would have been shocking if the news hadn’t already been spoiled), Gellert Grindelwald featured in Fantastic Beasts all along. After his disguise as MACUSA auror Percival Graves (as played by Colin Farrell) is done away with, however, Johnny Depp’s master villain is carted off to jail before we have even properly met him. We know he’s not going to stay there, of course, but we really hope he makes a much more significant impression when he does inevitably return.
For those not in the know, Grindelwald was the previous big threat to the Wizarding World before Voldemort. Unlike Tom Riddle, though, he didn’t want to wipe out muggle-kind but tyrannically rule them. Something he believed was for “the greater good.”
It’s an important distinction to make clear about the two villains. While Voldemort is basically evil incarnate, Grindelwald is just someone who believes they are committing necessary evils for the good of society as a whole. If handled correctly, he could be a more layered and fascinating antagonist than Voldemort ever was.
