This film is a look at how far people will go to retain their youth and beauty. I found it to be more satirical and comedic than horror, but regardless of the label, it was great!!
I do think the final 15 min or so were just too OTT. Hard to say exactly where I'd cut it off without spoilers, but probably when the lights come up on the stage show and all is revealed. No need for what follows, in my opinion.
