Exposition is fine when Hussie takes the time to do it properly and it serves as being exposition while still feeling like a conversation between actual characters. But Acts 5 and parts of 6 have been so exposition heavy that you can see where he starts to slip and the pesterlogs just feel like they're trying to get as much plot as possible out of the way instead of actual dialogue.
UU is pretty much the latter example there. An exposition robot hidden behind a souless facade of cutesy emoticons.
....okay I might be exaggerating a little here but it's still true to a degree
