As far as Kirby goes, I was lucky to start reading his work at a great time in the early 70s, when I could experience his best artwork from the Golden and Silver Ages as reprints, and his early Bronze Age comics month-by-month on the newsstand, such as The Fourth World and The Demon. As a kid I wasn't too critical of the differences in storytelling between the two periods that I demarcated above, always being more blown away by the power, energy and creativity. His artwork does begin to suffer in comparison from the mid-70s onwards, especially back at Marvel, but, thinking less critically and seriously now, his "flaws" are compensated for by very entertaining, unconstrained ideas and over-the-top dialogue, which I appreciate more now than I ever did as a teenager. It's the 80s period, when his art really declines badly, which greatly saddens me.
