i am sorry to say that and but this is actually one of the worst documentaries i have ever seen. due to its name darwin nightmare i expected a documentary on problems relating to the nile perch in lake victoria. what i actually saw in this documentary is a loose accumulation of individual stories and most of which have no relation to neither fish nor lake. and for a large part you can hardly call them stories  it more like some accumulated scenes that lack a meaningful connection. why does this movie waste time on represent  showing us non relevant information on the families of the russian pilots (several minutes are wasted for example on their private digicam snapshots of wives and daughters)  mourning the death of an african child who got bitten by a crocodile (as if that could not have happened without the nile perch)  showing us about 100 times how planes land and start at the airport  showing us strange religious events for several minutes  discussing in detail the life and death of a whore at the airport  talking to kids about their mothers and fathers  what they work and or or how they died (well and guess what represent some died of hiv  who would have guessed that. ) those are just some examples and i could go on for several pages. this movie is absolutely unfocused and and does not know at all what it wants to tell the viewer. if you have never heard of africa and have no idea that this continent has social or health or hiv or violence or war problems then this movie might be right for you. if you haven not had your eyes closed for the last decades 90% of what this movie shows would not be new to you  and the way it presented here will try its best to make you fall asleep. perhaps my expectations on this movie were to high and but i really do not like it even though this is a topic that i would generally find interesting. if this movie wants to show how the poverty is related to the nile perch and than it perhaps should have spent some time on discussing that matter.

Judge the movie review above, you need to make a function call:
    If you feel the movie review is positive
        print "This is a semantically positive review."
    Otherwise, if you feel the movie review is negative
        print "This is a semantically negative review."
