I went in to this film needing a remedy for the ailment that was 'If I Stay', and I guess it did the job to take my mind of that film. 'The Keeper of Lost Causes' is decently handled and has various details that keep your attention. The down side is that the film cannot mask what it is, and that is a standard police mystery film that does not stray from the formula and, every now and then, it decides to mix in highly over-dramatic moments (e.g. the bit where the kidnapper is identified in a photo - it makes you think if the was trying to be comedic such is the overblown nature of the scene).
While the film may be familiar and occasionally feel unbalanced, it had enough there to keep me occupied.
