Alright, plot-wise, I might just have to throw in the towel on this one. It is about... people, married, unmarried, love and desire. A lot of characters running in and out of eachothers lives. Since this is based on a famous novel (I think), there must be a lot of summaries out there that can help you along much better than I could.
Quite frankly, I was... confused. The whole movie is sort of based at a theater (more or less), where the scenes change constantly. It can be quite spectacular, I must admit, but also... confusing. As a period piece, this movie has paid attention to the details,... read the rest.
