UPDATE: Here's a spoiler for you. This film was produced 8 years ago and the island is still there.
I am moving my rating from a 1 to a 2 based on the cinematography, otherwise I would look for something below 1. Had the director chosen to tell the story of a 'man-gone-mad', then that might have been interesting but this dribble is just another propaganda film for the environmental movement.
What perplexes me is the assertion "the main island has lost 5 meters of beach front and that Manhattan Island is also at the same depth". Here's an inconvenient truth for you- ALL ISLANDS ARE AT SEA LEVEL! Here's another obvious fact that might present an obstacle to thinking people. Sometimes beaches erode because of ocean volatility and their lack of protection from the elements. Sometimes the plates of the earth sift and islands sink and sometimes islands rise because volcanoes erupt under the sea. There are a number of reasons that an island can experience beach erosion so why not explore all the reasons before jumping on one concept because it supports what uneducated people want to hear.
I love the passion of President Nasheed but it's passion misplaced. Passion for passion sake is acceptable for a child but for a grown man it is simply naive. If you think "An Inconvenient Truth" was science based then you'll love this film. If you see the hypocrisy of Al Gore purchasing beach front property in California then you might want to avoid this film.
