Haha yeah, that's definitely the right way to go, but the problem is not wrong expectations. He already DM'd a campaign for me a few years back and I knew what I was getting into. It's just not his style. I crave for gritty old-school dungeon crawling, while he loves narrative-heavy games where dialogue takes priority and backstories tie heavily with in-game events.
It's not all bad though, we still have fun, and my group takes turns at DMing - we all get to play what we like eventually, and offers variety in the long run. I would not play tabletop with any other group.
