Ron Marz plays games with interviewers to get his kicks. Try writing anything anyone would ever want to read, Ronny.

Has @ronmarz ever written a good story? I've never read anything from him that was not banal.

Indeed, his work in mainstream is particularly dull - whatever I read of his run on Green Lantern in the past 2 decades was tedious, and whatever I read since never made me feel like I was missing anything. As I've noted before, using established superheroines like Donna Troy and Jade as girlfriends for Kyle Rayner is pretty cheap too, reducing them to a lesser status rather than building them into their own agencies. Marz's Silver Surfer run wasn't great either (interestingly, since he left that job, his work for Marvel has been very rare).

But of course, it's his politics that are most problematic, ditto his smug, smarmy attitude. Even interviewers can be faulted if they haven't asked him any challenging queries.
