I haven't seen the new iWork UI yet but since I heard the same "dumbed down" criticism of every other version, I take it with a very tiny grain of salt.
I'm sorry if you like things more complicated. Most people don't.
No, I like things to be a useable level. I have the new iWork, I somewhat like the way it looks, but that doesn't mean I'm going to say it was a masterfully done UI. And when I say dumbed down, that's what iWork has always been in comparison. Office has some features that just make everything easier for people.
There's nothing wrong with it being dumbed down, though. Don't take that as being the insult that most see it as. I think iWork needs to have a bit more while Office's UI needs to be dumbed down a little.
