I don't care for any of the soundtracks you mentioned, except 2001, but the theme wasn't written for the film, so I can't count it.
Ennio Morricone is the best film composer of the 20th century, especially his music for Once Upon A Time in the West, Once Upon a Time in America, and my fave - The Good, The Bad, & The Ugly.
Jerry Goldsmith is also an enourmous standout.
Most overrated have to include John 'hack-man' Williams, and Danny 'I hope nobody figures out most of my scores sound the same' Elfman.
Mine too!
