Seriously? I needed to watch this before I died? (at least according to the older version of 1001) The only check mark I'm putting in the "pro" column here is that I never have to watch it again. Ever.
In the "con" column: I don't know exactly how to express my dissatisfaction with this film. I was really, sincerely hoping that Simon would kill Ariane at some point, that Ariane would run off and leave Simon (or kill him), that Simon would jump out the window, that they'd drive off the cliff on the way from the aunt's house while kissing . . . That something, ANYTHING, would happen. Her drowning is not satisfying. Ariane taking Simon down with her was the only solution I'd be happy with. And I was really only going to be happy if that happened within 10 minutes of the movie starting so I could watch a real film.
What either person was getting out of the relationship, I don't know. What I was supposed to get out of viewing their relationship, I don't know. Why it was in the book, I don't know (I don't have that copy in LA with me).
I'm going to assume that it being French and a looser than loose adaptation of Proust are the reasons.
I do know that I'm not posing any argument for it having been removed from the list.
