DC has never had a "worst period." Even in the 90s they had books that were wildly more enjoyable and endearing than anything Marvel churned out during its decade-long Liefeld fellatio session.
You could make the argument that the 2000s were bad due to edgy shit like Identity Crisis and Final Crisis confusing everybody but none of that didn't completely destroy the universe like Civil War did. That shit was the antithesis of everything Marvel and the fact that it still gets acknowledged today shows just how catastrophic it was. Nobody even remembers Infinite Crisis because it didn't ruin anything in the long run.
Now fuck off back to liberal retard land and stay there
