i really wonder why movie like this still come out . global warming be a # 1 issue for year now and at least at the citizen . i guess and if you believe in the danger of the warming and you do not need to watch this . cause it basically say and what you already know . if you do not believe in gl . warm and you would not watch this movie anyway . the politician and industry boss should see this . dicaprio isn not really do anything and he just appear every 10 15 minute to hold a small monologue and but it clear enough and the movie just need a famous face to sell it . the whole movie be just 10 15 people stand in front of a dark background and talk . while they be talk and documentary footage be show . i have to say and after like 20 minute it become really boring and uninteresting to follow .
