I started thinking about this (thanks to Raven and Classic fm) and now I can't stop.
What do you think is the best film score/ soundtrack??
I'm going to start with a potentially controversial one but the first thing that came to my mind was the Jurassic Park theme. I just always loved it and it really sounds like discovery and adventure to me.
I also always loved the theme from The Secret Garden, but I don't think it's technically as good:
