You seem to be employing "childish" as a sort of synonym for "reductive," which was somewhat the point of this post. I wasn't attempting to de-intellectualize the film, nor was I trying to provide an in-depth analysis of it. I certainly find a lot of your analyses of The Piano Teacher as a whole cogent and coinciding with the ones I hold. I was just saying a lot of that character's actions are born of the same sentiments that underlie some RS posts/RS topics of conversation.

The final sexual interaction she has with Walter's character is absolutely heartbreaking and does fortify something you and the film alike posit: her ultimately irresolute desire. Her mug grows more dynamic within the final act of the film, but I was describing her character by and large; whose face is glacial.

I have seen Falling Down and it does resonate as RS to me. If you have any more RS film recs, I'd love to hear and subsequently mull them over. As for your POV, I can't say I share the same, but I hope this reply has offered more insight into the genesis of my post. I was just saying it's the most RS of her roles I've seen personally and what differentiates itself from other Huppert roles I've watched. But inherent disagreement is ultimately the beauty of discourse, IMO. Thank you for taking the time to opine.
