It is certainly possible the writing has drastically improved since the very beginning of the run when I watched it and hated it.
But if a show took ten seasons to bring in some half decent writing you certainly can not take too much objection to other peoples' claims that it is not a very well written show.
Those kinds of shows do tend to have huge fluctuations in writing quality over a long series run. CSI, for example, had some very good writing in the first season. Then by the fourth season they were doing crap like, one random civilian figures out who the killer is, confronts him with this knowledge, then goes directly into a tanning booth in the next room, and is surprised when he gets murdered.
