We actually agree. His symphonic compositions are too simple and do not hold my interest. Since I really do not know much about music theory (I only go by what sounds good to my ear) perhaps there is something I'm missing here.
I would imagine that you like the Brahms German Requiem, yes? That piece to me is one of those rare few that I would gladly pay to play if I had to, and not the other way around. Same can be said about the Rachmaninov Second Symphony.
