I meant in terms of art style the marvel comics were awful. Some were drawn with that bad marvel superhero style rather than the golden age comic style of EC comics and Flash Gordon, that Lucas wanted. Even the scripts were bad and juvenile clearly aimed at children. Star Wars then had limited stories, and kids imagined stuff with their action figures.

The universe was not well drawn out and the marvel extrapolation was almost always wrong since Lucas did not have any involvement with the comic beyond whether or not Marvel kept the contract. I think Dark Horse did an overall better job, just like they did a better job than marvel with indiana jones.

The best marvels were written or produced by Archie Goodwin supposedly. i have very little knowledge of his work beyond the newspaper comics.

Adding Lumiya to me was almost as bad as black hole from the pre williamson newspaper strips. Again Lucas never outlined the nature of the dark side and the sith. Even the Eu up into the 90's got it wrong with calling them all dark jedi since at the time only vader was a sith Lord. Sidious was not the emporer at the time since their was only 1 darth.

But the Legacy novels and shadows of mindor very badly i might say retconned marvel and the pre williamson stuff back into the main EU canon. Which marvel never was a part of or was thrown out of canon due to its sillyness like the holiday special. Their was no overlapping between the novels and comics and movies like we have now, or any sort of cross continuity.
