I admit it - I watched the film purely because of the 2 gentlemen highlighted on the cover. While Cage was his usual restrained self like he's been in recent films and doesn't bring anything new to the table, Cusack did his best with the ill-fitted role which totally goes against his silver-screen character. The makers should have gone for someone like Stanley Tucci, who could have nailed Cusack's role to a T. Cusack at times seems too sweet and unbelievable to pull this off convincingly, which is the film's biggest sore point.
The events are supposedly based on actual stuff (and we get to see plenty of evidence before the end credits), but it's hard to suspend belief by that time. A serial killer who has gone through decades doing his stuff undetected and unnoticed, wouldn't become so careless all of a sudden, would he?
Nevertheless, recommended only to die-hard fans of the above two.
