Brief review: After the insanely-overrated "Saw" and the utterly mediocre "Dead Silence", Australian director James Wan finally delivers a solid and somewhat unique horror flick. "Insidious" deals with the intriguing and enigmatic subject of Astral Projection, and although it's not exactly an eye-opener, it reveals many unknown details about this supernatural phenomenon in a very understandable, believable way, without crossing the line into silly and ridiculous. "Insidious" may lack big scares and jump-of-your-seat moments, but it's just as creepy as its title suggest, thanks to its chilling atmosphere, some truly frightening images, and James Wan's dark and often sinister visual style. In addition, the pale-colored cinematography suits well the visual tone of the film, and the ominous music score compliments the overall feel of "Insidious". Having said that, the execution leaves much to be desired, as it seems like the director has been improvising too often while shooting the film, and the result is a good-looking, but somewhat unpolished 'final product'. The film also succeeds because of its top-notch cast. Both, Patrick Wilson and Rose Byrne give great performances as the anxious parents, but it's Lin Shaye as the freaky Elise that shines the most.
