My biggest gripe was the way the cat-motif was presented as incidental. Certain villains have their monikers thrust upon them (Penguin, Two-Face, Man-Bat), while others consciously choose to adopt a particular theme (Riddler, Mad Hatter, Clock King). Selina Kyle falls into the latter category. She adopts the feline mantle because of her affinity for cats, similar to how Batman adopts the mantle of the bat because it is his totem. But there was no mention of this in TDKR. She didn't have the cowl, the whip or the claws. And I may be wrong, but I don't recall her even owning a pet cat. Was she even referred to as Catwoman? She may have been, but I don't think she was. Granted, this approach was somewhat similar to the first two or three Catwoman stories in the comics. But the character has evolved a good deal since then.
I didn't feel there was any real chemistry between Hathaway and Bale either, and the idea of them suddenly becoming an item towards the end of the film felt forced and abrupt.
I also didn't see the point of the Jen character. Everyone assumed Juno Temple was going to play Holly Robinson, but she didn't. And her character just disappeared halfway through the film and was never mentioned again anyway. Seemed kind of pointless.
Much better than Halle thats for sure, which btw...anyone notice she also said "cat got your toung?" Thought that was a lil funny stab/homage to the 'Catwoman' movie...if it was at all.
