This show was very campy. However, the campiness made it funny. Robin's exclamations were somewhat corny. It was unrealistic that no matter how many times the "Villian of the Week" tried to kill Batman and Robin that they were never sentenced to long sentences for attempted murder.
The show used angled shots of the villian "headquarters" to symbolize the fact they were crooked. A little bit of imaginative planning there. Of all the villians, Cat Woman was probably the most interesting. She was part villian and part seductress. She never did succeed in seducing Batman though.
The addition of Batgirl in the last season added some spice to the show for a bit. Though it failed to raise the ratings enough to save the show.
At least the TV version of Batman was done in a way that kids could watch it, unlike the motion picture features that came out much later.
