I’m mostly indifferent to gender-swapped Kynes. There was a theory floating around that the change was made to make Stilgar Chani’s father, but IIRC, this ended up not being the case (someone with a fresher memory of the film can correct me if I’m wrong on this point). So an altogether arbitrary change, and mildly irritating on that front, but the actress gave a strong performance, so I wasn’t horribly perturbed. There were many other aspects of the filmmaking which left me far more cold. For example, Chalamet’s entire performance, his hair, and his stupid “Iron Man” moment.
