If there was some redeeming quality about that old show, something akin to how the Original Trek had a good ethical message or some such, I'd be much more accepting of it.
The fact of the matter is though, it's a cheese festival of nonsense. The only argument in it's favor is from the point of view of childhood nostalgia.
Yes, Batman may have been campy in the comics for a long time. But such was due to the society in which comics had to be published, not due to design. You couldn't have a dark and gritty comic in the 50s. Or on TV in the 60s.
The characters origins speak for themselves. A child orphaned at the age of 8-to-10 by a lone gunmen who robs and shoots his parents right in front of him, who grows up to pursue justice and, frankly, vengeance. That isn't light hearted. It simply couldn't be done justice for a long time.
It's just like the old Battlestar Galactica compared to the new. A show which in 1978 couldn't do the premise of a rabble of survivors fleeing a mass holocaust justice. Come 2003, boom. It gets done right.
Every argument in favor of the campy Batman, or the campy Galactica, or anything else campy for that matter, is based wholly in childhood nostalgia. In recapturing the wonder of something enjoyed as a kid. Not in a logical or reasonable argument of "campy is superior because A, B and C" or so forth. The only time camp is good is when you're a small kid and can't handle reality as well.
People want to remember the 60s show fondly? I can't (nor would I) stop such. That's everyone's right, to recall something fondly from childhood. I have such things. We all do.
But at least admit, it's a pale watered-down imitation of the character that existed because corporate big-wigs didn't think people, especially kids, where sophisticated or smart enough to deal with actual drama or any sense of reality.
IE, there can be only ONE Batman!
I'm glad that YOU can justifying why I like a TV show... You're WRONG, but I'm glad that you're doing your best to inception me.
I know for a fact that you're wrong because I enjoyed the hell out of the Cartoon Network's Batman: The Brave and the Bold, something that was camp as well. It was a fantastic romp. Energetic. Fun. And a great way for kids to have Batman be a hero in their lives.
