I completely know the feeling.
Years ago, when I finally found the original trade of The Flash: Blood Will Run, I knew that my years-long search for that OOP tome was worth it.
I’ve since sold that book, but the memory of searching for it, as well as when I finally found it, will live on.
Outside of online fan forums? I’m pretty comfortable with my DC comics knowledge. Here? I’m a total novice compared to many of the fine folks that post stuff day in & day out. Worst blind spot? There’s many, but given my love for Superman, I would say my Golden Age and Silver Age reading on the character need more work than most.
Well, I finally read Crisis on Infinite Earths:
So, I can cross that one off my list.
And I can no longer claim that I’ve never read a single DC event series.
I’ve now read a single DC event series.
I’ll get to the rest of 'em, I swear.
Eventually.
Someday.
Most of them suck. Day of Judgment is the one that sticks out by breaking the usual formula.
Even the other ones penned by Johns?
(P.S. I have a high tolerance level for suckage.)
My biggest blind spot is anything Flashpoint and beyond. But as I’m trying to read the DC universe as chronologically as I can. I’ll get there. Eventually.
He is the only one with any chance of success.
I took a break from reading rebirth stuff right before the Batman And catwoman wedding and now its been like three years and I still haven’t gotten around to reading the rest of Batman’s rebirth books
For me it’s Animal Man, Shade the Changing Man, and the whole “Death of Superman” storyline.
I’ve read countdown to final crisis but i didnt actually read final crisis
the killing joke, never read it and dont plan on reading it ever. i hate the joker, his only redeemable quality is being voiced by mark hamill
Also almost anything published before 2000
Not missing anything.
Has some good lines but mostly underwhelming.
You are missing great stuff from 1999 like when you crossed over with Stargirl.
Honestly, Killing Joke isn’t for everyone. And you aren’t missing much anyway.
Ok ok…. Well I hope I don’t get too much flac, but I never finished the Dark Night’s Metal storyline.
I started it, got about half way thru, but I’m having trouble keeping enough enthusiasm to get me over the finish line. 
I never even started it, and I am The Dark Knight.
