I read the book 'The Idea of You' prior to watching the movie and was left very disappointed.
Most of the book, with the exception of the storyline was changed for the film. It bothered me that they changed the daughter from 14 to 17, had her acting like a wannabe influencer with her friends and when she finally finds out about her moms relationship she's kind of cool with it. In the book she was not happy and it took a major toll on her, that is why Solène finally puts her daughter first.
UGH!! So much was wrong. From the meet cute, to the end of the movie, it was very frustrating!
If I had only watched the movie, I would have said it was OK, but still needed a lot of work to be a good movie.
