I remember on a cold and snowy early afternoon sometime in 1966, being dropped off by my dad at a run-down movie house where for only a couple bucks I watched ALL the Batman serials from both sets, and didn't get out until dark. I was saturated, of course, but it was fun.
I actually liked the cheesiness of the costumes and villains and the "Bats-Cave", because it seemed more realistic to me. In real life, how good could costumes really be, and how hard to be swinging around all the time. No, these guys climbed through the windows the hard way and got the crap beaten out of them in nearly every episode.
I watched some of these a couple of years ago on DVD with my daughter, and she and I enjoyed the episodes still, even though we laughed our way through them.
