When I hear the drumming of hooves, I don't think unicorns, I think horses. 
Red Lights is written and directed by Rodrigo Cortés. It stars Cillian Murphy, Sigourney Weaver, Robert De Niro, Toby Jones, Joely Richardson and Elizabeth Olsen. Music is by Victor Reyes and cinematography by Xavi Giménez.
A sceptical psychologist and her physicist assistant specialise in exposing fraudulent paranormal phenomena. But when one of the world's most renowned psychics resurfaces onto the circuit, it opens up a whole new can of worms.
It's a tricky film to recommend with any sort of confidence, this in spite of a high calibre of actors assembled for the shenanigans. For a good portion of the play it's a deft examination of the cons and belief values involving psychics and faith healers etc. The leading protagonists naturally have issues, and some secrets will have to will out, while Cortés has a keen eye for an other worldly vibe. Yet come the big reveal at pic's denouement there's a feeling of "really, is that it"? 
Ultimately this doesn't deliver on its promise or enhance the core base ideas on the page. It's creepy at times, even fascinating with the subject matter, but it ends up unfocused and confused and frustrating as a viewing experience. 6/10
