I must admit that Batman was my favorite tv show as a child. It wasn't until I was an adult that I realized the "campy" nature of the show was to keep with the comic strip. It's a shame the tv series didn't last longer, as according to google:
"Near the end of the third season, ratings had dropped significantly, and ABC cancelled the show.
NBC agreed to take over the series, but before it could do so, it discovered that hundreds of thousands of dollars of Batman sets had been destroyed. Rather than rebuild the sets, NBC dropped the project.
I find it funny that throughout the series, when Robin is brought up, Catwoman quickly comes to the solution that "we'll kill him.'"
