The critique is very good, with an enjoyable ironic and humorous tone. However, it oversimplifies dense concepts and events, specially on economics and history. Also, apparently it was misleading in what was really happening on the isle, and that being the case, fictional names should've been used, to make it clear that this is a representation of the problem of human consumption and not a report on a specific case.
A pointlessly thorough examination of one of the plights that humans experience, even in modern civilization, doesn't exactly make for an exceptional or noteworthy film, as it is portrayed by random people on the internet. This is tedious information one would likely learn in high school, which could have been better spent producing a good documentary. The whole thing is like an unfunny buildup for a plot twist!
