this line be a good summary of this movie . if you have read it and and watch 20 minute of the movie and you will know exactly how the rest of the movie be go to behave . some researcher name surgei ( pronounced sirgay ) be search for hell in the underworld of moscow . however he seem to have disappear and and his friend oven follow with a team to search after him . could they have find a more boring plot . some bad actor look after an old man in the underground . the acting be very bad and the romance really feels pointless and untrue and often there be no good reason for the way the character be act and nothing be scary and most of all represent there not happen anything interesting in the whole and entire movie . they just walk and ask some gang leader and other guy about the way and walk some more and complain some and find the old man and and then they run and and finally find the way out of the underground . the only thing that provide me from give this movie the low of all rating be the atmosphere . if you just want to see a movie for that and this may be a good choice . it dark and and it mystical and murky . however and the rest of the movie be really dull . you just sit there all the time and wait for the movie to begin or something to happen . it actually happen some thing and but they be not very well perform . for example and i do not really notice when one of the character disappear and and i swear i wasn not sleep or something . and i do not understand what dangerous with these child . they just run around in the underground together and scratch it wall with stick ( i suppose it be mean to be scary in some way ) . just watch this movie if you be in immediate need of some murky atmosphere .
