I agree that the 90's Flash helped paved the way for other such shows and that pulling off the super speed was an achievement for the time.
I feel that this show really got short changed by the networks, if it had been in a better time slot at the start and not always preempted I think it would have survived for another season or 2.
Netflix has the series on DVD rental, you need to search for
The Flash: The Complete Series
If you don't it will only display the current series.
I prefer the Flash suit from the old show over the new one
