Wait wait, are you saying that something has to be more complex for it to be really great?
John Williams is a great composer, and he is great because of his simplicity.
He certainly isn't he greatest composer, but he is very excellent.
Your 'education' has opened your eyes to things that 90% of everyone else wouldn't notice or even care about. That doesn't mean it's bad, it just means you can see area for improvement where other people just are quite happy with it.
I work as a radio producer, making commercials and promos for a radio station. I listen to other radio station imaging and commercials, and I'll complain about audio quality, poor scripts, bad reads, poor transitions, piss-poor promos and imaging, bad choice of imaging voice, etc. Do you know who else hears that? Other producers, and that's it. My wife has no idea what I'm complaining about, because she has no idea.
It doesn't make those other commercials terrible, just terrible to me because I know better. Everyone just shrugs. How can they complain about something they don't know much about?
Likewise, you might be paying attention to the bass-line or percussion of Indiana Jones, and everyone else is just humming the melody.
So what is your response? Make a pointless thread on the internet trying to get everyone to agree with your opinion of a well-received composer because you took some classes and think you know better then a guy who has been doing this for decades?
Or just let people enjoy what they enjoy! Heaven forbid we allow people to have differing opinions on something as subjective as music.
Geez.
