I'll start. The Batman television show, along with Super Friends and reruns of the 1966 Marvel Super-Heroes and the 1967 Spider-Man cartoon, were my "live action" (and given that three of my examples are animated, I mean moving pictures) introduction to the characters I was already enjoying in the comics. Even as a 6 or 7 year-old, I was certainly aware that Batman and Super Friends were watered down from what I was currently enjoying; the Marvel Super-Heroes was captivating, as I'd yet to fully understand the long history of Marvel Comics. But Batman was amazing to me -- it was so bright and colorful, and the over-the-top characters really drew me in. It was pretty whitebread story-wise, but the cliffhangers were enthralling! Now, looking through the lens of an adult, I certainly recognize it for what it was, and am fully aware of the damage it's done to the comic book genre in the eyes of the general public. Hey, is there an article about a movie heading into production that is not dotted with the obligatory "Bam!" or "Biff!"? Nope.
Now, the YouTube video I've included is certainly going to incite the haters among you, but I'd offer that for me, it's part of the nostalgic charm of the show. But it's on you now -- have at it!
