The religious symbolism, dreary mood, and operatic performances lend this suspense thriller a sort of parable-like quality. This is both what makes the film so fascinating to me and what is ultimately its downfall.
The ambition here is appreciated, but it is a bit too heavy-handed and thought it missed out pulling on some of its most interesting threads, such as Loki's character and Keller's family's reaction to his increasingly unhinged state as well as their shared grief.
Despite the film's shortcomings, the score is awesome, the actors had some great performances, particularly Gyllenhaal, and Roger Deakins burned some incredible images onto the screen. Some I'll surely remember, and for which I would watch Prisoners and its bleak but almost beautiful atmosphere again.
