Being the objective of this documentary to raise awareness and support DiCaprio's activity as a "UN messenger of peace" and environmental activist, I believe it really achieved its goal as it is truly a breathtaking, eye-opening film which urges the viewer to strive for a change.

Throughout the documentary we are presented with shocking information, images and educated people's opinion on the matter (like world leaders and scientists) which adds credibility to it. Leonardo DiCaprio and his team do not spare criticism on some of the biggest countries (like the US) policies and on the fossil fuel industry.

Leo's charisma and ability to persuade and entertain the public allied to his drive as an environmental activist just leaves you glued to your seat thinking what can you do to make a change. I believe this really is the kind of information that should be more out there and DiCaprio's celebrity-status, as well as all the other people interviewed, is great for visibility.

If anything, I just wish this was a mini-series to know even more about this issue the world is facing, which might just be the biggest one it ever did...

I am glad that this documentary was made, even though I felt it was talking to someone other than me. The movie is focused on America (even though what it preaches is relevant all over the world), and much of the information is not really ground breaking if you are already concerned about the environment. I am not complaining about this, as that is probably the best target audience to try to reach for a documentary like this. There's no reason to make more documentaries preaching to the choir.

The documentary itself is mostly well made. Leonardo travels from one place to the other, and talks with some big names. Some of it feels kind of irrelevant, and the best parts is when Leonardo talks with people who are not that famous, especially the one subject that shows her frustration. Some of the places he travels are interesting to see, though it's mostly quick visits, and at times they feel more like backdrops than important set pieces. Despite the documentary jumping from one theme to the next, it holds together quite well, and Leonardo's journey functions well as a mean to take the viewer through all the information.

Personally I would have liked a documentary that was a bit more science heavy, maybe like a combination of the nature trips that Leonardo goes on here, and the presentation from Al Gore's film. But I can understand why they went in the direction they went here, and I hope it resonates with a lot of people that have not thought much about this.

Before the Flood is a movie in which Leonardo Di Caprio travels around the world and shows us how it is being affected by climate change, reinforcing the fact that we, the human beings, are responsible for it. Through out, his journey he also meets experts and important people who are also concerned about this issue. This truly impacted me and left me thinking about how we are destroying our planet and how we are running out of time.However, it also inspired me to take action from the place I am. In this case I should start consuming differently and voting for leaders who will fight for climate change. I think the most thought provoking person whom he talks with is Dr. Piers Sellers from NASA. He created a model simulation of the earth that shows all the changes our planet has suffered among these years and how each area is being affected in different ways. I would give this movie a 10 because it is a way of showing many people reality and inform them about global warning. Besides, I like the fact that above all the information and facts he gives, the movie is also moving. It makes you feel fear and guilt, but it is also asking you for help. It impacts you in such a way it inspires you to take action about this big issue that is not only affecting us now, but also the future generations.
