We rent videos. I could never have gazed upon The Thin Blue Line, because of its insistent pain, had not its protagonst, in reality, been released last week from his Texan prison. But I wanted to hear Philip Glass's score. Glass has found his niche. The Rashomonian repetitions in the script would have been boring were it not for Glass's boring music, music which because of its monotony ties up, locates, and heightens an otherwise banal scene.
