Guest stars, weddings, characters battling life-threatening illnesses, babies, etc., etc., blah, blah, blah. What you end up getting are overhyped crap-fests, shark-jumping episodes, if you'll allow me to used that weary phrase. What it feels like is the network wrestling control away from the people who create it on a week to week basis and creating a false and forced "event" show. NBC seems to be the biggest offender in this regard, although maybe that's because of their shameless promotion (ie. "Will & Grace - The Wedding"). I guess it works though.
