Veronica wisely begins with the emergency recording from the events inspiring this tale in order to establish its credentials as a 'true' story and to keep people from tuning out through the slow build of a standard possession movie. And it it as standard as they come, from start to finish. The only thing unique about this film is the Spanish setting and an exceptional performance from the main actress. The interaction between the younger characters playing siblings is excellently portrayed and layered, adding levels of watchability even if the supernatural elements are rote. The creepy scenes are effective, if nothing particularly original, subtly blending CG and practical effects. The direction and cinematography are also quite good, the whole thing is very nicely presented, it just not presenting anything new.
