There were a whole bunch of really not great choices made throughout this process (see above), and even some of the most basic aspects of the film really rubbed me the wrong way. Mostly because it seems like the creative powers that be are shoe-horning plots in just to add tension. Plots that don't make sense! Take, for instance, this strange supposed love triangle between Newt Scamander, Theseus Scamander, and Leta Lestrange.
In the film, we get the vague insinuation that Newt and Leta bonded over being outcasts while at Hogwarts, but never get any confirmation that they were lovers. We also don't learn how Theseus and Leta ended up together; we just know that they're somehow engaged and somehow in love. Were meant to believe that there's tension between the three, that Newt might love Leta, or Leta might love Newt, or whatever. With so much in the subtext, though, I mostly thought "?????" the whole time.
That's just one example of the sort of hodge-podge plotting that meant to made the film more exciting. Same for all that tension between Queenie and Jacob about getting married. It just doesn't make sense, and it's sloppy.
