The homages to Se7en got really tiresome (spoilers for both films!)
You can tell the director/screenwriter was anamoured with Fincher's film a little too much. First there was the title sequence at the begining done in a similarlly jagged, off kilter style (only from the perspective of forensic experts rather than a psychopath). Then there were the crime scene investigations of grisly aftermaths, complete with "shock" remains flopping out at "unexpected" moments. Around that point I started to wonder if the killer was Ethan Hawk, Jolie, the other cops... or someone that had yet to be introduced... then half-hour later, Keifer Sutherland made an an un-credited appearance, a la Kevin Spacey in Se7en! Sure, Sutherland wasn't the killer, but it seems like too much of a coincidence that the film-maker's motivation wasn't the same... to surprise an audience with an un-credited, yet well known actor playing a bad'un.
There is even a decapitation involved (Gena Rowlands instead of Gwyneth Paltrow) and Jolie is discharged from the force in the same way (I imagine) Brad Pitt's character is at the end of Se7en...
and to make things even more ironic, Jolie started work on Mr & Mrs Smith shortly after this film was released and we all know what happened then.
