That is the power of this movie, cause I think of all the movies I saw from 1977-83, and how many of them I just grew out of, but not this movie, and not the trilogy either. I saw it at 5 years old that summer, and I have never loved a movie as much since. I am so lucky I didn't get tainted seeing it like so many newcomers as part of the saga, and losing the whole power of the standalone movie.
Lucas, your being a jerk now, but I tip my hat to you for this masterpiece in 1977.
