I think I'll just try reading the originals.
If your looking for a nice new edition, I got one a little while back. It's a nifty illustrated edition, with the first three novels. "John Carter of Mars: A Princess of Mars, The Gods of Mars, The Warlord of Mars" hardcover, from Library of Wonder. Some really great illustrations by Thomas Yeates.
Just checked out the newer trailer. Looks a little better. There's some scenes where Deja Thoris looks regal, pretty close to the comics.
I was never happy with any of the comics. Even the newer ones. They just never seemed to capture the feel or look all that well. Maybe it was just me, or something about the original novels, but I loved Conan and Tarzan comics well enough, they seemed to translate into comics pretty well. Maybe I had higher expectations for the John Carter stuff, for some odd reason.
Where was that from, the old pulp magazines? Or a paperback edition?
