First off, that TNN show was horribly promoted. Like Heyman said, The Rock could've walked on and it wouldn't mean a thing, because nobody would've known about it. Get a hype machine behind an ECW show and we'll see.
And obviously, the key to a full-out ECW restoration isn't rehashing Dreamer and Sandman again and again. That's the sort of one-off deal that won't sustain interest. It's more a matter of rekindling the spirit of ECW in how the fans are treated, the workrate, the making something out of nothing, all that.
