Even though many people have never included Raiders Of The Lost Ark as one of John Williams's best scores, it is in fact a great classic that is in the same league as Star Wars, Superman, and Jurassic Park.  The Raiders theme has been heard everywhere and sounds like a mockery of the campy-sounding action movies of the past, and the secondary theme for Indy sounds mysterious and truly suspensful.  What makes this score so great, though, is because it sounds like a mix between Star Wars A New Hope, and Return Of The Jedi.  It sounds heroic and bright like New Hope but dark like Return Of The Jedi.  Marion's theme sounds like and almost starts off like Princess Leia's.  The Ark and Nazi themes are my favorites.  The Ark theme sounds mysterious and vague until its powers are released on The Miracle Of The Ark, where it sounds powerful and out of this world.  The Nazi's theme sounds truly menacing and rivals even the Imperial theme of Empire Strikes Back.  I recommend this to any fan of John Williams or action-lovers.  It is a true classic in film scoring.
