There is certainly some truth to that fact, and it can be even more if you're familar with comics largely through the ill-fated boom of the early 1990s. It was the best of times; it was the worst of times. There was a lot of crap, but there was also a lot of stuff that managed to get out that wouldn't have been able to in more -- hmmm -- conservative(?) times. And a lot of that, both good and bad, still manages to hang around. And a lot of the good is silly, as is a lot of the bad. But I was, honestly, expecting you to come back and claim that they are inherently silly, and it seems a waste to throw away my tens of seconds worth of research finding a counterexample (mostly spent looking at my bookshelf), so I'll give it to you anyway.

Fax from Sarajevo, by Joe Kubert. I picked that one because (1) it's amazing and (2) it's by someone who has produced stuff that could easily be considered silly (Sgt. Rock, Tarzan, lots of standard superhero fare, and, really, pretty much anything you can think of). I think that everyone should read it. It's really great.

Also, I've been wanting to ask if any folks from that area of the world have read it and what they thought of it if they have. Takers?

(In defense of Malibu, though, I enjoyed a not insignificant portion of their Ultraverse superhero offering, back when that happened. It had been a while since there was some good, straightforward superhero stuff. But some of it was definitely just plain bad. I think your statement could more accurately be used to describe the early days of Image Comics, especially, say, any Liefeld crap)
