Without any single line of words, this movie's strength lies on cinematographic arrangement, musical composition, and viewer's own interpretation. Ron Fricke done a terrific job (especially on his city nightscape) and Philip Glass's composition is wonderful. However, viewers' unfamiliar with the film's narrative (post-capitalist critiques on technology) might find themselves' confused with a long still-shots, slow-motions, and fast-forwarded scenes the movie delivers. I personally need to take some time to connect the dots between the scenes presented.

The lack of dialogue, though, gives the movie more chance to be re-watched, as it presents an open-ended interpretation - which seems to be the director's intention. And if you can't watch it for the narrative, at the very least you can watch it for the wonderful music.
