Cool hand Luke. Opinions.

Cool hand Luke is a great movie when you are looking for an anti-establishment film, but let's take a closer look at certain scenes in the movie. The very first scene where Luke is cutting heads off of parking meters. First ask why is he doing this? Later in the movie Luke says he was settling an old score, but with who? And what for? After that why did he let himself get caught? With this many questions and so little answers this early in the film I did not like it to begin with. But others seem to disagree both the NewYork Times and Roger Elbert speak highly of it, saying that it was a good movie.
