My biggest issue with Hathaway's Catwoman is that she never uses a whip .
(I guess another pedantic issue is they never once call her Catwoman in the movie).
I am trying to remember if Julie Newmar/Eartha Kitt/Lee Meriwether ever used a whip either. So not having a whip isn't an instant disqualification.
Julie Newmar did use the claws though. I remember a scene where she cut a hole in a glass case using her claw.
