I easily watched the entire movie, and even back-tracked a few times to catch dialogue. From a qualitative perspective the plot is clear and the action is a medley of silly, cute, heroic, provocative, spoofed cliche, forward-thinking, wicked (but not overdone) entertainingly acted scenes. The movie is not too long, and the tempo is appropriate. The premise of the movie is based on serious reality--conceivable tragic implications of reckless human activity conducted in low-Earth orbit. Quantitatively, I am unable to complete viewing 80% of new-to-me movies that I give a shot. Therefore this movie ranks better than 80% of the distribution of my new-to-me movies. And, 80% expressed on a 5-star scale is exactly equal to 4 stars.
