Toxic masculinity: the movie. There is no reason to root for this romance. Barnal's character is super unlikable, and the fact that Gainsbourg lets him get away with all the stuff he does is nonsensical. There is not even tragedy to make him sympathetic. The film is visually cool and should maybe work by reading it as satire, but it's such an uncomfortable nightmare. Also, what's with all the random homophobia?
It's a really charming story with really whimsical set pieces and interesting characters that really drives home how much imagination is a part of our lives. Gondry just has it down pat when it comes to dreams. Loved Gael Garcia Bernal and Charlotte Gainsbourg in this as well.
After Eternal Sunshine, Gondry was given to the keys to the castle when developing the visual style of his follow up and, for better and for worse, this is the result. The switching between wild oneiric imagery and more mundane interactions between Stephane & Stephanie (the rest of the cast acting as a Greek chorus) is initially fun but grates towards the end, esp. as the screenplay lacks Kaufman's character depth.
I haven't seen this in many years but I remember it being quite cute with the stop-motion and playing with dreams. It also introduced me to Charlotte Gainsbourg <3 Unfortunately, I had a lot of problems with the character of Stéphane, a manchild who behaves very inappropriately to Stéphanie throughout the film.
