Since the Nostalgia Critic reviewed nostalgic television blocks like Nicktoons, SNICK, The DIsney Afternoon, Fox Kids, and Toonami (even though he didn't watch much Toonami), there is another block he needs to look over: JETIX!!! I alos made a fan review idea of this here.
Did Doug Walker himself watched Jetix before, or never has? If not, there could be somebody who can give him a hand and explain how much of an impact Jetix made (the same way Malcolm, Tamara, Walter, and Heather explained Toonami to him.)
