Yes, yes you are the only one. /thread
I'm sure there are others who didn't like it either, but regardless Ulduar was some of their best work ever (past Flame Leviathan) with some of the most diverse, interesting and challenging content, with some of the best environmental design and theme.
There are a bunch of people who didn't love the whole Frozen Wasteland theme of Northrend either, and many many like myself who loved it to bits. For example for me MoP is the single worst environmental/theme design ever. It is boring, cluttered, and dips into Asian aesthetics which I really dislike and try to avoid like fire. I'm very very happy that for most of SoO they stayed away from MoP aesthetics altogether.
