Well has it? or am I just stuck in the past? If it has, why do you think it has? For me Wrestlemania used to not only be the pinnacle (It still is I suppose) but it used to be where major storylines culminated and significant moments in wrestling history occurred. Thinking back to the first 20 wrestlemanias and they are littered with such moments including Hogan/Andre, Savage/Hogan, Hogan/Warrior, HBK/Razor ladder match, Austin/Hart, Austin/HBK, Austin/Rock x 3, TLC and the triple threat at WM20 just to name a few. On top of those matches, the first 20 shows were littered with other moments/matches and were largely enjoyable shows. Even the duds like WM4, WM9 and WM11 are noteworthy for one reason or another. After WM20, these moments and matches get a bit thin. WM21 and 22 were good shows TBF but the only noteworthy items that immediately jump to my mind post WM20 are HBK/Taker x 2, Edge/Foley, McMahon/Trump, HHH/Taker x 2, Brock ending the streak and the Daniel Bryan show at WM30. I could rattle off the main events of the first 20 manias (as well as other matches) without even thinking and the next 5 after that with some thought but thereafter I struggle to even remember what was on the shows. For me the reason is that it just doesn't seem as special anymore, it is over engineered, way too long and just feels like a longer version of any other show they do albeit in a stadium.
