i will keep this short a a movie like this doesn not deserve a full review . give the setting and this movie could have be something really special . it could have be another 28 day later or even a blair witch projectthe first 20 or so minute of the movie i be really excited and directer do a decent job with cinematography and suspense and although i do not think he manage to capture true eeriness of an empty london underground . character be a big let down . our heroine in this movie be a worthless piece of crap and and you really do not care if she die or not . a many people have say before and i be root for the homeless people and the black guy and who manage to give me a chuckle or two ( whether intentional of the writer or not ) . the main villain and be keep in the dark for the first half of the movie and but when he be reveal i be really disappointed . i would not spoil it but let just say my 10 year old sister could probably beat him in a wrestling match . all in all this be just another mediocre horror film which fall into the trap of follow a simple hollywood formula . this film have a lot of potential but really fail to hit the mark . just to highlight how lame this movie be and the character in this movie have at least five time to finish off and kill the main villain . instead they run away .
