I shouldn't keep attacking Brian and Kelly...they were the showrunners and head writers so it makes it easy, but the show did have a bunch of mediocre writers. I think Don Whitehead and Holly Henderson wrote a bulk of the episodes as well, remember them being one of the better ones?
Well I don't agree with you on Brian and Kelly but I do my share of attacking Miles and Alfred, so I can't really talk.
You'd have to name a few episodes Don and Holly wrote. I'm drawin' a blank on them right now.
