"[With] shivery and indelible images....Like most haunted-house films, INSIDIOUS is a contraption, but it's one that won't let go of you." -- Grade: A-
Total Film - 06/01/2011 3 stars out of 5 -- "INSIDIOUS is genuinely unnerving, offering some of the best-orchestrated scares since Oren PARANORMAL ACTIVITY Peli forgot to shot his bedroom door..."
Kim Newman - 06/01/2011
"Wan plays the first act, almost subtly, evoking the GRUDGE or PARANORMAL ACTIVITY films....[This is] a scary movie."
SAW franchise veterans James Wan and Leigh Whannell team with PARANORMAL ACTIVITY writer/director Oren Peli to give the familiar haunted house story an exciting new twist with this tale of a family that moves into an old house and begins to suspect they are under siege from otherworldly forces when their young son inexplicably falls into a deep coma. As devoted parents Josh (Patrick Wilson) and Renai (Rose Byrne) struggle in vain to uncover the root cause of their son's condition, the stress of the situation gradually begins to take its toll on their once-strong relationship. Later, when darkness falls and specters appear to reach out for them from the shadows, the frightened parents realize they're dealing with powers beyond human comprehension. Barbara Hershey and Lin Shaye co-star.
