Nah it's cool.
The problem is you need more than nostalgia because otherwise you do stuff that gets incoherent.So, I can't say restarts are WRONG. After all, I liked the Silver Age because I responded to it positively as a child and the Post Crisis because it did the same for me as a young adult. There is a certain nostalgia that creeps in with age to hold onto what you cherish from your early years. That's why you'll find older people want more to keep the Silver Age elements and a younger group the Post-Crisis and an even younger group something more recent.
Take The Flash. The first one was Jay Garrick, not a successful or important hero. Then you had Barry Allen, the Flash of the Silver Age who was popular in the '50s but declined in favor after that, and then during COIE the editors asked Wolfman/Perez to kill him off because they thought he'd become dull and stale. Then Mark Waid decides to upgrade Wally West as the Flash and a good part of the Flash mythos developed around Wally (i.e. the Speed Force and so on) and Wally became *the Flash* when the JLU cartoons came, and then DiDio and (sigh) Johns brought back Barry for no discernible reason other than personal nostalgia nor did Barry's return lead to stories that couldn't be told with Wally.
And now the result is that the classic Flash mythos developed around a legacy now centers around the guy it was erected above and that made no sense. It's totally subtractive.
