I disagree. Some of DC's best comics can be confusing to many new readers...and, even some old ones. Some of DC's best titles are below:
The Justice League/Justice Society crossover currently going on in their respective titles even has current readers confused about many of the Legion members that have shown up.
Checkmate is totally confusing if you haven't been following along. Sure, with the current crossover with Outsiders it's been greatly dummied down...but, it still has elements that will leave a new reader scratching their head. (Plus, in both cases, a new reader has to shell out cash for not only one title, but another book, greatly diminishing their comic funds.)
Countdown still expects the reader to know about all the Crisis' of times past, even if they are giving a dummies guide in the end of the books. But, in this case, a new reader has to shell out 2.99 each week, further reducing the amount of comics they buy monthly. (And, some scenes involve further reading, as with the brief tie-in with the current Justice League/Justice Society crossover.)
Another favorite title, Supergirl and the Legion of Superheroes, would be extremely confusing to a new reader. Hell, I've been following this title since it Supergirl joined, and I still have trouble with all of its members and their past.
So, that's just an example of my favorite DC books. If they wouldn't be confusing (and costly) to a new reader, I guess I'm an idiot.
