>Dark Knight Returns
>Watchmen
Comic books that inevitably went on to ruin the DC comics universe and superhero comics in general because of their influence. The dark serious grounded tone? The 'deconstruction' and 'muh realism' of comics like The Boys? All because of these two comics.
>Crisis on Infinite Earths
A good comic that ruined DC comics. Because it's influence went on to make it so that DC had no consistent '616' continuity like Marvel. Because if DC ever finds itself in a corner where the fans don't like a story decisions, or they write a character into a corner? Rather than sticking to them and making the best of it like Marvel does. They can just reboot and wipe the slate clean.
