Obviously this film isn't an outright movie about movies, and that's not what Carax wanted either (based on interviews I've read), but you can't help but pick up on all of the references (Merde from Tokyo! and Celine's mask at the end of the film from her previous roll in Eyes Without a Face).
I just loved the look of the film, wondering if any of it was real, the different film styles, the surreal moments. It raises so many questions, but never left me feeling like I absolutely understood nothing of what was going on. Instead I was constantly questioning, trying to figure it out and then feeling pretty good about what I got out of it. Yeah, there are holes and that's probably a good thing, it makes you want to keep thinking about the movie and what you take from it. That's a mark of success in my eyes.
I was reading one critical analysis that raised a question I had and I wanted to poll your opinion on this: Was the scene with the daughter he picks up from the party real? It's the only time in the film he drives himself and, more importantly, she's the only other character that he really talks about all of his "appointments" with besides Kylie.
Speaking of Kylie, that scene was hard to accept as reality as well, especially given the moment she breaks into song. When that happened, my heart kind of broke a bit for Mr. Oscar as I realized that once again none of what was going on around him had any stake in reality.
Crazy crazy film and I'm so glad I saw it. I'll have to pick it up at some point, because I'm certain I'm going to find myself wanting to watch it often down the road.
