Batgirl was a wonderful character! She was the best thing about the otherwise disappointing third season, and she became an enduring character in the comics whose popularity has continued to the present day. She was one of the strongest female characters in '60s TV, up there with Mrs. Peel and Agent 99. She was a smart, independent, heroic woman who could do everything Batman could but without the benefit of a multimillionaire's resources. She was utterly fearless and didn't feel she had to leave the fighting to the menfolk. She was a terrific role model for the young girls watching the show.
Christopher, placing Batgirl on the same level as 99 or Peel is an insult to those characters. Batgirl pranced around, referring to the stereotypical "women's intuition" or tea leaves (and it was not her being facetious) as her crime-fighting tools, instead of intellect & training. For batgirl to be presented that way in the late 1960s--after the advances made by Peel, 99, Honey West, Cinnamon Carter and others promoting intelligent, strong female characters, Batgirl was like something out of 1960, instead of the 1967-68 season.
If that was not bad enough on the intellectual level, Batgirl--supposedly a costumed superhero--contributed what to the once raucous, exciting bat-fights (pre-Batgirl) seen in seasons 1, 2 and the 1966 movie? Slow high kicks and pirouettes, followed by some sassy remark.
The character appearing in the comics of the same period was much more advanced, and did not seem to be an oddity amongst the endless superheroes and villains of the day.
