Both. Both can be very fun sometimes. As long as they are not at the same time,

I love both, but I like dark and gritty Batman more. It can have some sillier elements boiled in though.

I think there can be a nice compromise of the two.

It obviously depends on the story, but I prefer a noir detective Batman with sci-fi elements, like robots and lasers.

I like both. I personally see Batman as a mostly dark character with a little bit of campiness in him.
