Thank you! I have rather drifted out of DCU fandom since I wrote this, and haven't revisited the source in a long time. The only concrete thing I remember as a difference between 120 and beyond is that the writer changes from Jon Lewis to Bill Willingham, and I very much dislike Willingham's work (and attitude towards fans).

But there is so much of the canon that is completely amazing, and I stopped reading around Robin 135, so I don't know how things have changed in the last five years. The post-reboot world may work really well for you. Enjoy exploring the canon and the fandom!
