People who like those shows help keep talented people employed, and that's good. I'm not someone who believes that we'd necessarily be seeing more shows that would be more to my taste if some long-running hits didn't run so long nowadays. Not that we can be sure yet how long this show will run, but it is doing very well, as broadwaybacker mentioned, and I would imagine it may well run for at least three or four more years (and quite possibly a good deal longer than that).
