i wasn not particularly impress by this movie that have lackluster music and only last 40 minute . thank god and because i be fall asleep . i make excellent use of time lapse photography to display the passage of time in the movement of light and shadow and people and water and cloud and etc . unfortunately and that all it be . my preference be for it predecessor and the excellent koyaanisqatsi make in 1983 at 87 minute and to prove that a sequel can be good than the original and powaqqatsi make in 1988 run 90 minute . try them both .
