Great watch, could watch again, and can recommend. This is a great survival horror story that really rachets up the tension as the situation progresses. The idea of being hunted in the subway with homeless and rats around is very intriguing for me. Sadly, like most good horror movies, I can't talk about most of it without spoilers. I will say this has some great concepts in it and the over all story structure is very well done with some good twists / surprises in it. It may not be a feel-good love story, but it would be a pretty bad survival horror story if it was.

Ok, I confess that the background story and the movie cover attracted my attention. And when I saw Christopher Smith name here I expected something (Severance, Triangle, I thought I had something good to expect) I will be brief and make a full spoiler here: the premise is good, the execution not so much. It is very inconsistent, like a person will be "forgotten" in a subway station? People don't clean the trains into the night hours? A psycho child from the anti-Blitz tunnels of WWII? No one misses the presence of people (especially workers) in the subway? Come on, that's too much. Plus Franka Potente (Run Lola, Run) is really bad here. At least the dog is ok. :) My score: 4.0 (barely) out of 10.0 / C -
