Blackhat.
Saw this got absolutely slated as a turkey upon cinema release but I think there's a lot to like about it. Yes, especially in it's first act, it's faced with the problem every tech/cyber thriller has in that a guy staring at a computer screen telling you what's happening is not that exciting, but there's some fabulous moments in it including many of Mann's signatures.
7/10 and worth a look imo.
