I fucking hate the book L'Amant. It's so fucking boring and the narration is ass. I had to read it twice for school and the second read through i didn't even realize that i had already read it until halfway through because it created 0 memories inside my head.
I have a tough time imagining the movie, which i'm now learning exists, could be any better. But i guess since the narration was so phenomenally incompetent at describing literally any situation or action, having images is probably a big step up.
