THE WALL is an interesting--though people who want a really tangible storyline and/or fast action and suspense might choose the word "boring"--little film.
How to describe it? Quiet, somber, original, going deep without trying too hard. Fantastic in the most literal sense. Well-acted and well-filmed: The Austrian Alpine scenery, perhaps the single best thing about THE WALL, is just spectacular. Still, there are a number of plot-holes and incomplete threads, things that don't add up and are not apparently supposed to--"Kafkaesque" is another word that kept running through my mind as I watched.
Though it's nothing great, I'm happy to have seen THE WALL and, most of all, am eager to read the original novel by Marlen Haushofer, which, even if it doesn't make completely logical sense, based on the reviews, apparently has more sense of completion.
