The 'Death of Superman' is a classic. It was a huge event that had a massive impact on the Superman mythos. It showed Superman's vulnerability and the world's reaction to his loss, making it a very memorable story.
Some of the best graphic novels according to CBR could be 'Watchmen' by Alan Moore. It's a complex and thought - provoking work that deconstructs the superhero genre. The art and storytelling blend seamlessly to create a dark and engaging world.
One of the best is 'The Dark Knight Returns'. It shows an older, grittier Batman coming out of retirement. His fight against a new breed of criminals and his complex relationship with the Joker are highlights.
