I really wanted to enjoy this film but it just didn't work out. I was hoping to see a realistic and perhaps even educational story about relationship-conflicts and adultery but, to my regret, I saw an incredibly pretentious and isolated film...All very stylish and dared... I won't deny that... but overall un-involving and illogical. It's about a young woman who goes out on a sexual odyssey because her lover does NOT want to have sex with her. The obvious decision would be: brake up with him if it really bothers that much!! But no, she doesn't and therefore we get to see a series of semi-pornographic sequences and a whole lot of philosophical mumbo jumbo! Writer/director Catherine Breillat really tests one's attention span here. In general, I love films that are slow and atmospherically built sequence by sequence but this Romance X was a bit exaggerated. Sex sequences are explicitly observed and then you receive a whole analysis of them...You either appreciate this style or dislike it. Also, it didn't bother me that much, but Romance X clearly is a "woman's film". The portrayal of several men in this film isn't exactly anything to be proud of. Either way, there are better things to waste your life with...
