I completely agree and was also something I clocked when reading. Even today I’m rewatching some of the stuff I watched when I was a kid and am finding some teeth grinding, uncomfortable moments and was like, really!? That was in there?
Also I found it quite interesting that they included Detective Comics #1 as an example during Yang’s essay at the back of Periodical #2. Quite a big acknowledgement from DC and was really happy to see that from the publisher.
