The author tried too hard for this one, too many themes, too many rough breaks, too many radically different influences. Shocking scenes and visuals for shock value only are so cliched and not worth watching. I think that stylistically it would've been better to go full kitsch in some parts, but I guess that the issue of the budget.
The pacing is so inconsistent, first half of the film is promising, the middle is boring and annoying, I couldn't wait the film to end for at least half an hour of it. Film has a lot of long scenes without any reason for it, should've been at least 10 minutes shorter.

There are some really good stuff, those topics that deal with basic needs of a human individual, to be loved, to be accepted, to be safe.
But that [spoiler]serial killer stuff, Alexia's psycho motivations[/spoiler] aren't explained at all, this plot choice served as a cheap set-up for the rest of the film. Lot of gender topics were touched upon without ever deciding what to do with them.

The final scene is biblical and probably saved the film from irrelevancy, although I hoped that [spoiler]Alexia would get killed with that damn hairthing by Rayane[/spoiler].

Don't get how so flawed film got so many important awards. The competition must've stunk.

I'm not sure I enjoyed what I just watched, but I'm going to give it time to process before I make a rash decision on my score. What a crazy ride of a movie this was. Even as someone who has seen Jumbo, a very similar film in subject matter, this one still took me off guard with how sporadic its story and narrative structure was. It also had me squirming multiple times with its absurdly squeamish body-horror segments. Very weird, very French, with a lot of symbolism and "under-the-surface" meaning that I will now spend days unpacking.
Never change Cannes, never change.

Edit: No, I've sat on this for a day now and I'm just not coming round to its strange, albeit wholesome and unique hodge podge of messages and themes. [spoiler] I enjoyed the juxtaposition and coming together of the two main characters, one never having a childhood and the other having their parenthood stolen from them. I enjoyed the themes of gender identity, returning to trauma as a comfort after living under it for so long, and the role of sexuality as a processing mechanism for all this.[/spoiler] While these are very well represented and conveyed articulately, bringing them together in this strange horror/drama/art piece package just didn't connect for me. I can appreciate its parts seperately, but all together they just don't sing from the same hymn sheet in my opinion. Much like Midsommar and Possession though, I've had fun parsing and researching all the intricacies of this movie after the fact, so it has that going for it. I await Julia Ducournau's next foray into cinema, she certainly makes fun and unique movies you won't see from any other director.
