An aspect of fair use is that it doesn't interfere with the actual market for the thing. A movie analysis, even one that heavily uses the work its analyzing to illustrate its points, is not usable as a substitute for watching the film if one wants to get the experience of the work. In this case one is taking art for sale, and using it as art for sale. Its possible some can view high prestige art and low prestige art as separate markets but I don't really. In my mind its more akin to taking a novel and abridging it to a novella. Same fundamental market.
