Yep, those Gold Key comics were generally badly drawn and written. Some of 'em are fun though. I liked the one with the mummy in it. Some of the painted covers were awesome. There's the one with Barnabas & the Golem coming up behind him, which I always thought was really cool. Even though most of these comics were pretty bad quality-wise, some of 'em were fun to read.
A new DS comic would certainly be of a higher caliber story and art-wise. I'd love a continuation of the classic series, with the characters and locales based on the original cast.
