One of Dreamcatcher's few memorable moments concerns an extra-terrestrial life form erupting from the bottom of an unfortunate gentleman while he's on the lavatory. It's an entirely appropriate image, since down the toilet is exactly where this, the latest in a long line of poor quality Stephen King adaptations, is headed. The bizarre plot has four childhood friends on a hunting trip rescuing a deranged oddball who, it soon emerges, is host to some sort of alien parasite. While they attempt to evade the monster, the military - in the shape of Morgan Freeman - arrives, determined to eradicate all trace of the shape-shifting beastie. Despite a screenplay co-written by William Goldman (who brilliantly adapted King's Misery), initially effective atmospherics from director/co-writer Lawrence Kasdan and creditable performances, this is soon hobbled by poor quality CGI and an abysmally incoherent final act. As usual, King fans are advised to stick to the book.

Four childhood friends reunite for a hunting trip in the Maine woods, bound by a psychic force born from a childhood friend's dreamcatcher. They find themselves caught in a grotesque alien invasion that twists memory, sanity and reality into something far more sinister.
