I'm curious why TBC is so popular.

I've finally reached level 60 and gone through the gate. But I have to say that Outland looks really barren, everything is swarming with annoying monsters, and the quests are all about killing countless monsters. Not much variety. Maybe my expectations were too high because TBC has such a huge reputation, but so far I really can’t understand the hype. I’m only level 61 now, but I haven’t really had any fun at this level. What exactly is it, for you guys, that made TBC so great back then and even today?
