I like 4E Forgotten Realms. What I don't particularly like is that it is necessarily Forgotten Realms. The new Neverwinter, Thay, and Athkatla, the introduction of Abeir, are all great places. But I don't think they needed to be Neverwinter, Thay, and Athkatla. It seems almost gratuitous to change the setting into a new setting with old names instead of just creating a new setting.
And the Spellplague was just crap. It could be nice as a setting itself. It ends up feeling tacked on at times. Like the setting has just become too busy. This city is now filled with refugees, this one has become destroyed, this one taken over by undead, and the political climate of these have shifted dramatically, oh and there was a near apocalypse recently, y'know, for flavor.
