See, that is how they should diss WCW. Not with this Confidential "WCW sucked and couldn't push anyone, Bret Hart ruined it, etc." but with witty stuff like Nitro having some Nitro Girls and complaining that they "serve no use to me, now dance for 15 minutes I need to fill some time in my schedule".
What's at all productive about making fun of a dead company?
Nothing.
It'd just be better if it was witty.
