A "grim loner in a bleak setting" is who Batman IS. He's not Superman. He's not Captain America. He's BATMAN. And I'm really sick to death of people trying to resurrect Adam West in the name of "fun". The blue and grey costume, the sunlit settings, the lighthearted attitude, the very existence of Robin... it's just WRONG. It's people like you that caused Shumacher. The misplaced nostalgia for the Silver Age and 60s TV show is what led to "Batman and Robin". And every time we think it's buried for good, people like you and Shumacher and Morrison dig up the corpse. It's a pathetic joke that refuses to die.
Batman: the Animated Series NAILED what Batman should be. Mask of the Phantasm was absolutely definitive, from the art deco stylings to the inherent tragedy to the pitch-perfect characters and settings. They got it right. Batman is NOIR. He's a 40's hardboiled detective in superhero form. The sunlit happy silly "Batman and Robin" is an abberation.
For all that's holy, STOP trying to bring it back.
