I watched this movie y'day and must say it is a good one...the lead actress Shannyn Sossamon is natural in depicting her fear and nervousness...BTW i just happened to watch another latest movie of her "One Missed Call" and that too is good... there are many horror movies which deal with gore and bloodshed only, this is not that type, rather kinda chased down by a maniac in a deep dark tunnel can breakdown anybody's nerves... however everything became clear towards the end and you gonna like the climax, its undoubtedly different only that i can say... When I am writing I saw this one got an average rating of 4.7 which is very unfair with this movie...I would say a decent 6.5 should be given... only one comment about the music, it could have been more spine chilling....
