These were the days when Marvel Comics were consistently fun. Possibly the last of those days, as the onslaught of the 90s (Get it? Onslaught? Heh.) turned the Marvel Universe into a place of doom and gloom and dark despair. And epaulets. Jackets with epaulets. Yeah. ‘Cause that’s what super-heroes are about.
If you want to find comics that capture the spirit of fun and optimism that you find when you go to see a Marvel Studios movie, your best bet is to go pre-1987. That’s not to say that there aren’t some dark times for our heroes during those runs—the death of Gwen Stacy, the Secret Empire, the Dark Phoenix Saga—all angst-ridden and brooding, yes. But still the ultimate feel was fun and light and triumph.
