Well is he? Bash me for saying this but John Williams may be a great composer but I'd rank him as "one of the best" not "the best". Of course, I go through my many periods of listening, first I'll shuffle through a bit of Danny Elfman, then a bit of Jerry Goldsmith and then some David Arnold and Hans Zimmer and then John Williams. But it's really difficult to say who is **the** composer of films. Every composer has their own unique style and John Williams has his own. Of course it's like algebra, you can't compare things that are greatly different. Elfman to Williams? Not a chance in comparing who is better, it's just that Williams seems to be more recognised as a great composer than most others unless one goes through countless amounts of time studying another composer's music of course. So in conclusion, Williams (to me) is just one of the other great composers who has placed a great impact on us like Goldsmith and the others.
