2002 and 2003 WWE has some great stuff worth checking out.
2002:
-Hogan/Rock had some classic stuff leading to Wrestlemania X-8 and seeing Hogan put over a heel Kurt Angle and Brock Lesnar cleanly later in the year was great to watch.
-Brock's monster push to winning the world title and having great matches with The Rock at Summerslam and the HIAC match with Undertaker at No Mercy.
-The Billy and Chuck duo teasing being "gay" and the 'gay marriage' that resulted later in the year on Smackdown was entertaining.
-Great matches between RVD and Eddie Guerrero/Chris Benoit (separate feuds) over the IC Title. The RVD/Benoit match at Summerslam is especially great because it also has the backdrop of the Raw/Smackdown brand wars since Benoit won the belt and then jumped to SD, leading to RVD challenging him to an inter-promotional title match at the PPV in an attempt to reclaim the title and bring it back to Raw. The RVD/Eddie ladder match for the belt on Raw is epic, too.
-Booker T./Goldust pairing was funny.
-Return of Shawn Michaels and the awesome HBK/HHH match at Summerslam.
-The debut of Rey Mysterio and some great cruiserweight action within that division.
2003:
-Brock/Kurt Angle feud
-Brock superplexing Big Show and the ring collapsing as a result (an idea later reused at Vengeance 2011.)
-Goldberg/Evolution feud was pretty good.
-Kane's unmasking that led to his return as a monster and his feuds with RVD and Shane McMahon (the latter which was very awesome and made for some of Raw's best segments in 2003, IMO)
-Vince McMahon's Mr. McMahon character was also at his most entertaining this year IMO. His stuff with Hogan, Zack Gowen, Brock, Linda, Stephanie, Undertaker, etc. It would be too long to type out in full but Vince was out of control on SD this year and it made for some of the best segments throughout the entire year.
Both of these years get shit on by a lot of fans but it's mainly because it was the first couple of years to come out of the post-Attitude Era and a lot of people were simply butt hurt to see that era end (myself included at the time.) But both '02 and '03 are underrated and have tons of great stuff. They're two of my favorite years in WWE history.
