I suppose it all comes down to what an individual classifies as "quality". What I look for in any TV show is entertainment and characters I can care about. Stay within the boundaries of the show's premise, don't repeat the same story over and over, and give me reasonably well-developed characters. I have a hard time watching any of the modern sitcoms, although The Simpsons will keep me entertained. As for the dramas I watch, I suppose I consider them "quality" because they fall within the parameters I set for enjoyable TV.
