It just never felt that way to me. It's an album that stands still. Tie Your Mother Down is Death for Two Legs, Prophet's Song is White Man, Best Friend is Somebody to Love, and so on. It just didn't move things on. There was a lot of excitement about Night at the Opera, forward momentum, so I expected more. In fact, for me, Queen topped out at Night of the Opera, and it was a path downwards after that. They had some good songs of course, but as an album band they became a vehicle to plug some tracks around the hits. You could, but I'd no agree. Opera was clearly a level beyond anything that came before. They had mastered the studio, and were able to use it as a tool like never before. Prior to that they were a rock band with some intricacies. With Opera it was full blown rock cabaret. Night at the Opera is an experience, imo. It hangs together like a movie, feels epic. Nothing they did before got to that level (and keep in mind, Sheer Heart Attack is my favorite overall). It was a road to maturation - and Opera was that.
