Insidious sees the parties behind two horror heavyweights - the creators of Saw and the producers of Paranormal Activity - join forces for an almighty fright-fest. Yet while the result of their unholy union is chock-full of scares, it fails to hit the horror heights of its predecessors, creating the requisite atmosphere but never quite delivering on its promise. A twist on the clichéd haunted house genre, the film finds teacher Josh (Patrick Wilson), pianist Renai (Rose Byrne) and their three children moving into a beautiful new abode. But while on the surface they appear to have achieved domestic bliss, there's something horribly amiss in their new home.
