Just like Miami Vice, Mash, and a few other Complete series. A few change from Double sided discs to singles, have better reviews extras etc. What do you like better. Waiting for the Complete set. Get mad when you find out after buying all seasons that a Complete set is out? For me I sold 5 individual sets cause of Double sided discs, Hearing of a complete series, Individual seasons coming out again with the probs fixed ie double sided to singles. I got upset when I couldn't buy any KING OF QUEENS sets where I lived so I awaited on the news of the complete set. Bought it. Same with SEINFELD but never bought into it. Then bought the complete set. Some have said in another topic they just get mad when they've purchased all seasons then that series comes out better in a complete package, etc...... But not all series do that. Im hoping Cheers and Frasier don't come out with a complete box set.
