Just for the record, I figured out the final twist just seconds after the film started.
Right when the scene of Grindelwand showing his back to the camera faded out and the scene of Percival Graves in the exact same stance faded in. They basically telegraphed it right then and there.
Stupid me just couldn't figure out why no one seemed to recognize who he was and thought maybe they didn't know exactly what Grindelwald really looked like.
For some reason it didn't occur to me that he changed his entire appearance via magic because the hairstyle seemed so similar with the exception of hair color.
