i'm not saying it's all horrible... he just cant seem to hold his empire as coherent/cohesive/... as he used to.
He appeals to such a wide swath as you said, that sometimes he seems to mix them, the lines blend and that's not always good when we are talking about the very linear, graphic, minimalist armani.
Now collezioni gets all young and fresh (instead of stiff and precisely cut as it normally is) emporio sometimes is all glittery and grownup, and yet some others it's sporty and dressed down...
For the record, I must admit I like some of the stuff he has recently done in his atelier collections, which are not so safe anymore and that becomes him a lot. It's so good to see he can actually sculpt and pull off some shape, and even do it in bold colors!
