That first part was absolutely amazing in every single way : cinematography, control of the narration and the time, like I was REALLY liking it. It make this second part even more frustrating to watch : everything went too quickly, it's like Corbet didn't know how to end his characters' arc and even some screenplay's choices were .... Questionable to say the least. However, it still had some beautiful shots but yeah, I was really bummed by the downgrade in the writing quality.
All in all, it is a good film, especially for that first part but it is not THAT great
