the "everyone having a storyline" part was part of what made it great. That just meant you had a reason to give a s**t about every part of the show. Without it, you have filler matches that dont mean a thing.
Additionally, everyone had a storyline because the roster was that deep...and they were actually using the undercard and lower titles to groom new stars.
the undercard from 97-00 included HHH, The Rock, Hardyz, Edge, Christian, Owen Hart, Shamrock, Farooq, Bradshaw, Jeff Jarrett, Mick Foley
also, technical skill <> a good wrestler in ring. technical exhibitions with no story telling are garbage. The key to being a good worker in ring is being able to tell the story of the match. Back then almost everyone was doing that.
was everything gold? of course not, it never will be.
but in terms of depth of talent, storylines, crowd energy and excitement, it's untouchable. it was the last era to realize what wrestling is at it's heart...a soap opera.
