For the quality of the documentary it deserves a high rating. It's extremely well done, with tons of data that are easy to understand as it's all well explained. The documentary itself is not something that will cheer you up, quite the contrary, as we're all just witnessing how we slowly, if you can call slowly a century in earth's time, destroying our planet by poluting it like there is no tomorrow. Recycling is the only solution. Banishing plastic completely would be better but we all know that's just utopic as there is too much money involved. The negative reviewers on here just prove that stupidity is all around us and it's not going to get better as the population will reach 10 billion by 2050, and so tons and tons of more polution. Glad I have no children.
