Really? I feel like Hardy showed more acting talent in Bronson alone than Kunis EVER has. Not to mention Stuart: A Life Backwards, Wuthering Heights, The Take, Warrior, etc.
You're right, range isn't everything in acting, but it is at the very least least evidence of talent. And Hardy has displayed a ton of it, going all the way back to Black Hawk Down.
And for the record, it has absolutely nothing to do with him being in Batman. I was already rejoicing when Nolan first cast him in Inception because I thought he was one of those rare talents that big directors needed to take notice of. I'm glad they have.
