As mentioned SD! was very good in 2003.
The main event scene was Brock Lesnar, Kurt Angle, Chris Benoit, The Undertaker, Big Show(before he was a lazy peice of shit, and was capable of a good match with the right opponet).
You had John Cena on his rise to becoming the next big star for the WWE, and arguably his best year as a character.
WGTT tearing up the tag team divison having good matches week in and week out.
The return of the U.S. title.
And overall good wrestling weekly.
