I must admit that the writing was spotty in the series, but the age produced some of the most creative authors of our time and paved the way for the acceptance of sci-fi in general. I just find myself re-reading the older material more often than any new stuff because the new just doesn't have the (can't think of a good descriptive word)_____; fill in the blank. (Flair, Intensity, Innocence, Wonder, Speculation, etc...) Ah...the good old days..... David
