Terrifying film. Showed us the 'dark' side of the spirit world.

Rating: Null/10 (13 February 2016)

A young couple leads a quite and dull suburban life with their children. Quite suddenly, certain occurrences (strange noises, things falling off) start to take place. Tragically, the couple's younger son collapses and falls into a coma. The doctors cannot find any probable cause and eventually the kid remains in this condition and stays in bed all the time unresponsive to any external stimulus.
Weeks later the mother sees a strange figure of a man entering in the boy's room but suddenly disappearing. The mother of the husband intervenes and suggests that a psychic (medium) professional may provide help. The psychic, a very sympathetic and eloquent middle-aged woman, comes in and after reviewing the household and premises suggests that the sick boy has certain abilities that make it extremely vulnerable to evil entities. Moreover, the kid has fallen victim to such entities who captured the kid's mind/spirit and do not allow it to regress back to the real world. There is a disbelief from the couple but eventually they agree to allow the psychic with her partners to start a procedure of bringing back the boy from the other 'dark' side.
'Insidious' is a very good film. Refreshing, well balanced, very scary and brought certain new elements in the horror genre. In particular, the importance of the spirit world in our everyday lives and related beliefs which are cherished more in the American-Indian societies and also in far eastern Asian mythologies.
There is some resemblance with the old film 'Poltergeist' directed by Tobe Hooper and produced by Spielberg, but I thought that 'Poltergeist' (indeed a very good film) went in a different direction and did not go too far inside this spiritual world of the 'dark' side. 'Insidious' directed by James Wan, instead, took such a path and gave us a terrifying viewing experience.
