Scarlett Johansson may not be a bad actress, but we have no reason to think she's a good one either, nor do we have any real reason to think she's a good lay. The only reason she got popular is because she was in Ghost World, and Ghost World wasn't even that good. Johansson appeals to the usual pedophilic corpuscles in all moviegoing men. I'm not saying she's a bad actress. I'm just saying that the only reason any Scarlett Johanssen scene is good is because there is someone else in it who could potentially fuck her.
