Theatrical cut: cult in making. Director´s cut: Michael Mann´s another masterpiece - without sentimentality (eg. gone are dialogues about characters past), with improved structure and overall flow of picture. Video and audio quality are better than old studio Blu-ray release, adding to Mann´s mixture of realism and impressionism. Old bonus features - three documentaries - are informative, not your usual EPK style. Two new interviews are great but it´s bummer that nobody interviewed composer. New audio commentary is funny and contains good info for average Mann´s fan. Missing some thorough video essay about three different cuts or something about Mann´s style, how Blackhat differs from other cyberthrillers. Essay in booklet is short but dense. This release is not as great as two disc edition of Arrow´s Thief (Mann´s debut feature) but inclusion of director´s cut is worth the price.
