Errikos, you're upset aren't you. You have your tastes, and I don't share them.
If it was just taste, fine. BUT YOU ARE THE ONE WHO SAID JOHN WILLIAMS IS A FRAUD. Not that you don't personally like his music but the sweeping statement he is a "fraud." That is total bullshit. You are engaging in the lamentably common practice of elevating your own opinion into a universal aesthetic principle. Trust me on this - you have a right to your opinion - warped, ignorant and ludicrous as it is - but it is definitely not universal, nor a principle of any kind. You need to understand that.
For someone to praise John Williams as an orchestrator and writer of "catchy tunes" but a total fraud is the height of total ignorance as well as arrogance. Williams first of all does not do his own orchestrations. Whoah! That's a shock, huh? You thought he wrote it all out himself, eh? So you're wrong to begin with there. Secondly, his music is the MOST SYMPHONIC OF ALL FILM MUSIC since Korngold in the 30s. Why am I mentioning Korngold to you? I am certain you haven't the slightest idea of who that is. (Quick! Google him!) But anyway, even Williams' scoring is precisely in the style of the heyday of symphonically scored and developed films of the 40s studio era. This type of scoring DOES NOT USE CATCHY TUNES but instead relies upon complex development similar to symphonic form or Wagnerian leitmotival operatic structure. Mancini is the prototype of the "catchy tune" composer, not John Williams. Do you know who Mancini is? Or did I just waste some time mentioning him also?
Also, you missed the whole point of this thread - not that Zimmer music is ineffective as film music - I STATED THAT SIMPLISTIC MUSIC CAN BE EFFECTIVE EVEN THOUGH IT SUCKS AS MUSIC. I was disturbed by the lowliness of this music as compared to the great film composers. Their music is effective for the films it scores, but it is also interesting musically. My whole point was that Zimmer's success and its obvious and inevitable copycat deluge have taken things far down at the same time he has been elevated to the position of a great musician like John Williams - and that is exactly what he truly is despite the rat-like gnawings of vermin who try to dismiss him as a "fraud."
BTW - Appalachian Spring by Copland is based upon a traditional Shaker melody which Copland DID NOT COMPOSE. That is the melody you heard and instantly concluded John Williams stole.
One other thing - I detest people who say "film music shouldn't be noticed." You're bringing up a tone-deaf moron who didn't notice music in a film doesn't mean a damned thing. So what? A slug crawling on the floor of the theater didn't notice it either. As Max Steiner put it - if nobody notices it why bother to write it?
