Looking at those above gifs.. Anne Hathaway just does nothing for me. It's the same feeling I get when I look at Halle Berry as Catwoman. Yet instead of looking silly she just looks awkward and weird. She also isn't anywhere near pretty enough or has those 'feline' qualities that Catwoman should have. Catwoman is supposed to be a stunning beauty (unless you want to count those Frank Miller's Year One where she is a bald prostitute).
And if that's supposed to be imitating Julie Newmar, just look at the way the mask fits over her eyes - it doesn't look right:
