The Flash is one of my favourite characters. As a kid, I used to read the Flash at around the tail end of the Infantino run. The "Trial of Barry Allen" arc, I think. I still remember the issue where the Flash was racing against time to save Fiona Webb, who sealed herself up in a sensory deprivation chamber after being trapped in a rockslide or something... I don't know. I might be making all of this up. Still, I was fascinated by this guy who, at the point I first read about him, had been through a hell of a lot.
I read about him next at around Crisis. In fact, I read the issues where he was already dead first as I couldn't find the issues to fill my run until later. He always seemed to be a guy doing huge and great things, and paying the price for it.
Hm. It's late and I seem to be rambling. I can probably talk about the Flash for hours, though. I'll leave it with this: my favourite Flash story of all time is Mark Waid's "Return of Barry Allen". Not only is it a great superhero adventure story but it also contains everything essential about a great story, period. People interested in the character would do very well to get a copy of that story and read it.
Anyway, that's it.
