As opposed to all the comics since that have taken wild swings with Hal and Ollie? But I take the point, Denny's Hal is slightly different from John Broome's--although Neal Adams did a great job on Green Lantern. However, I think Green Arrow was greatly improved--given that Ollie had already done much of his changing in THE BRAVE AND THE BOLD 85 (from Bob Haney and Neal Adams) and in issues of JUSTICE LEAGUE OF AMERICA (from Denny O'Neil and Dick Dillin). I loved the Green Arrow's new look so much and I still think it's one of the best costumes. I wonder where Green Arrow would be now, if there had never been that big change in his look and his character--they made a super-hero that was practically on the garbage heap, into one of the most important DC creations of the 1970s and beyond.
And where would Elliot S! Maggin be if he hadn't been inspired by Denny and Neal's Green Arrow to use Oliver Queen for his college writing assignment--which ended up being picked up by Julius Schwartz for GREEN LANTERN 87? Which was the big break that got Elliot a job at DC.
I'm curious how people are reading these stories. All the modern reprints have been terrible. The Batman stories being the most drastic in changes to the art--to the point where I really don't think you can appreciate how Neal Adams developed Batman over those years. But even the modern reprints of the Hard Travelling Heroes are quite gawdawful with terrible colouring that is nearly blinding when I look at it. And how many people can afford to buy the back issues--I only have most of them (still missing some GREEN LANTERN issues) because I bought them at the time or only a bit later in the 1970s and 1980s. Now, anything with Neal Adams art, from back in the day, is not easy to get, unless you have deep pockets.
