All of which makes Prisoners a movie that, compelling as it is, falters as its story becomes increasingly convoluted in its latter stages. Its contrivances suggest that instead of that father-and-son deer-stalking opening, they should have gone fishing - because it sure is red herring season for much of the movie.
Back at the start, that's Dover and his teenage son out in the woods in a prologue which establishes him as a solid dad, albeit with a paranoid survivalist streak and probable NRA leanings. He and his wife (Maria Bello) are friends with the Afro-American couple (Terrence Howard and Viola Davis) up the street.
When their daughters Anna and Joy disappear, the first prime suspect is Alex Jones (Paul Dano) who is possibly mentally handicapped.
Loki eliminates him as the perpetrator. But Dover takes matters into his own hands, attempting to find out what Jones knows in his own brutal way.
Cue the film shouting: Would you do the same in the same circumstances? How far would you go?
Jackman's aggrieved dad is impressive. But Gyllenhaal's Loki, facial tics, unexplained tattoos and all is, oddly, the more believable.
He's one of the more memorable screen detectives of recent years.
His presence - much like Jodie Foster's Clarice Starling in Silence of the Lambs - compels you to believe in Prisoners and not drown in its darkness.
