Mary (Rachelle Lefevre) moves in to an apartment complex in Puerto Rico to escape her abusive ex who is none too happy about the divorce or the restraining order placed against him. Soon after, she's plagued by a barrage of phone calls from someone who identifies herself only as Rose. Slowly, their casual conversations veer toward an ominous direction, and one by one, people around her start dying or disappearing after she tries to cut off contact with the deranged caller.
If you have the patience to wait out the first 20 minutes, The Caller is a decent, straightforward mystery and suspense type thriller with reasonable acting and the welcomed absence of any CGI. Most of the scenes are shot at night or in Mary's dimly lit apartment, adding to the overall gloomy and grim tone. The movie is meant to inject you with fear, not with a quick jab to the jugular but, via a slow and steady stream. The borrowed time alteration theme from Frequency has its pitfalls - don't over-analyze and you won't be bothered by the plot holes.
A refreshingly unpretentious flick that relies on old school horror techniques (no gore or guts, no obtrusive soundtrack, no deafening sound effects) but, sadly, easily forgettable.
