I doubt any of us think he could be anything close to a journalist. It would just be good if the actors and writers could talk freely, uninterrupted before he switches topics. I wouldn't have even minded if occasionally he were to interject, to challenge something that was said, if there were a contradiction, but then, like others said, that would require that he do more than cursory research, be able to dig deeper.
In any case, like I said, if there were a full year if clear quality, complete episodes from the mid 80s, I would be watching that channel, and wouldn't care what he does.
I notice that Watros seems to be intentionally playing against the literal writing and character-type (or what exists of such a poorly defined character). I think that's gone a long way in making this character digestible and even somewhat sympathetic (which she still often was as Annie even when the writing was stacked against her). That's the skill of a talented actress.
