I had it at #92 out of 93 shows i ranked.
Its fun and all, but its pants really.
The only show I ranked lower was Sliders.
Pants is something good right?

Since I was the high voter on the show at #39, I'll testify for the defense.
It's mostly a nostalgia pick; Batman is the second show (after Walt Disney's Wonderful World of Color (unranked)) I can remember watching as a kid. I distinctly remember being upset when my pre-communion class conflicted with one of the nights it was on.
As a child, I liked the action and preposterous cliffhangers which I analyzed with my friends at Fairview elementary school during recess. When I re-watched as an adult, I appreciated the campiness, casting choices and pop art visuals with bright colors, dutch angles and superimposed fight sounds. The show fell off in the third season with one-parters featuring Batgirl but for a while it represented the zeitgeist of the mid-60 as well as any show from that era.
