Justman's memos show he could be incredibly snarky. He was overdramatic in a funny sort of way, I've read a fair number of memos from the show that most people haven't seen, and while Justman often had very valid comments, his ideas for "fixing" stories were often bad...he wasn't a writer and it shows. None of this is to say his notes on the City should be dismissed. He makes some very valid points in general.
