Marten Weiner doesn't bother me too much, because I think he fits the character. Of course, I am under the impression the character is a complete psychopath.
I have this dread that they are going to start moralizing stories this season. They threatened it a bit last season when discussing about the bombing in Birmingham and civil rights in general. Luckily Betty put it back on the straight and narrow with the line, "I hate to say this, but this has really made me wonder about civil rights. Maybe it's not supposed to happen right now."
