Perhaps one of the most puzzling aspects of the new film is the way it treats the characters we meet in round one. Take, for instance, Tina: she's a huge part of the action in Fantastic Beasts and Where to Find Them, so much so that she quickly becomes a favoured love interest for Newt. This time, she's randomly dating to another Auror, whom we never meet. What's more, her role has been sliced, taking her from a lead character to a special guest appearance at best.
Queenie, on the other hand, is given a prominent role, but not one I enjoyed. She's all over the place, completely helter-skelter, until she does the unthinkable and joins Grindelwald's side, becoming evil. The Queenie we see in the final scene is unrecognisable. She's lost all the things that made her great in the first place: she's introduced as confident, quirky, and loyal, which makes her 180 to the dark side not only confusing, but also highly unrealistic. The insecurities she feels about her relationship with Jacob — who clearly loves her — as well as her own telepathic abilities that make her seem "crazy" are far from being good enough reasons to turn her into a villain; the film barely scratches the surface of her feelings, not even bothering to include a confrontation between her and her sister, an Auror.
