With the exception of Arrested Development and I am starting to worry if that is a good idea, I am against reunion shows because they never work out very well. I think though that a Married... with Children reunion would be great. It never really had much of a story line so you can pick up with them anywhere at anytime and I think everyone would feel right at home.
Ed O'Neill was asked by E! if he would be willing to have a reunion and he said he would be up for it if everyone else would do it. I think that despite Christina Applegate and Katey Sagal having their own shows that they would be willing. I think they loved it and would not shy away from it. Make it happen.
