The old Marvel Mars books were fun, 70s-80s, but the new ones are really bad, I only read one in the store but Mike's right even the interior art was odd.
We were talking about the lawsuit at the LCS, and the owner recommended the Dynamite books, he said they were selling way better than the Marvel one. I picked up a few last week, and I gotta say they are pretty good. I got a Flash Gordon anthology too, some really fun comics. I haven't read the Tarzan one yet.
Seriously, the Burroughs estate may be on great terms with Disney, but they would be better served going to Dynamite with the comics license than suing them.
