8 Times WWE Hit The 'Reset' Button
4. The WCW Reversal
Whilst WWE warred with WCW throughout the late-'90s, the company's loyal followers were continually indoctrinated to the idea that the lads from Atlanta were the absolute enemy - to the extent that DX famously even 'laid siege' to the company in a 'tank' (actually not a tank).
So it was hardly surprising that fans in the Tacoma Dome for the 2 July 2001 episode of Raw vehemently booed the efforts of Buff Bagwell and Booker T during a dry run of a proposed WCW takeover of the show's final hour. The match itself was not grossly hideous, but the mere concept of the dead rival daring to supplant the war's winner was anathema to an audience which had sided against them.
It almost feels as if WWE set the WCW experiment up to fail.
