Fans of Cormac McCarthy's The Road will love this movie. Fans of waterworld will enjoy it.
I cant believe the complaints of these other so called reviewers. One complained that it was unrealistic the survivors weren't rescued. Did they miss the part where it says world ending typhoon? This is a post-apocalypse movie, not a natural disaster one. They also complained it was unrealistic people would resort to violence. Not that movies about world endings apocalypses are known for their realism, but none the less the depictions of savage actions by desperate people are one area where this type of movie shines to illustrate, relative to being a movie. So another unintelligent nitpick.
Another reviewer complained to the effect of that the movie was boring, due to the buildings the of and around where the movie takes place being partially submerged by the waters. That confuses me because that essentially was the movie, that was the plot, it provided a unique and original setting for the story.
There are several low rated star reviews that nitpick and complain in ways that seem almost as if they had the film on in the background doing something else. I on the other hand really enjoyed watching this movie, both for the setting of a partially drowned city, and for the story itself. It's a shame it's not rated higher because I really think it deserves it. If you enjoy the depth and humanity and struggle exampled so poetically in the bleak cruel worlds built with dark simplicity in movies like "the road" then you will find that same brilliance here.
