There are two reasons I would like to see "Blackhat": The cinematography and Tang Wei. I'm curious to see how Tang Wei is in an American movie after she was blacklisted in China. She seems likes a capable actor so I would like to see her get new opportunities.
For the cinematography, it was decent for the most part. There's still something weird in both Blackhat and Public Enemies where there are a couple of hand-held shots that look like they were shot on cheap camcorders, and it's such a terrible contrast to how the rest of the movie looks. Also there are a few foot chase scenes that are hand-held and the picture just shakes too damn much.
Tang Wei does a decent job in a pretty thankless role, IMO.
