There are numerous films that did poor box office but deserved to be seen. This isn't one of them. I guess the number of positive reviews reflect movie goers' need for mindless action rather than well-developed characters or logical plots. The set and mood of the piece are spot-on -- dismal and claustrophobic -- but other than a handful of people running from monsters not much happens. Too bad more attention wasn't given to the script. This could have been a thought-provoking and insightful cautionary tale.
