I can't like Frank Miller and not like grim n' gritty. Though Millers work is far more stylized then most grim n' gritty comic fare to the point where its more escapist which is why I like it.
Also, telling Marvel fans you like older Marvel comics and not digging newer stuff makes them question your tastes. Why do some fans, both marvel and DCs, find they need to try and make a deal out of someone not liking their current books or characters? Especially when you're not bashing them, you just don't care for them.
