I never heard of Christo before watching these films, so it was a treat discovering them, and his art projects at the same time. These documentaries are very interesting, all of them cover his projects from pre-production through finish. If it sounds mundane, it's not, as the movies are also very entertaining for various purposes: one, the actual projects are beautiful, and it's a treat to watch people work together to put them up. two, Christo and Jeanne-Claude themselves are crazy and interesting people to watch. three, none of these projects were easy to get permission for, the process and heart-aches they go through to get permission is all accounted here. The subject matter is interesting, but the documentaries are also dramatically compelling in their structure.
At one point, after wrapping the pont neuf, two strangers in Paris argue about whether or not this is art. The man in favor of it says "you and I don't know each other, if this project never materialized, we'd never meet, ever." This is the essence of Christo's work! He brings people together to celebrate the spirit of self-expression. Ridiculous or not, art or not, it is important an achievement and it provokes discussion.
