Sometimes, when I read reviews about movies on IMDb, I see patterns in the writing. Similar text, similar structuring and similar indignant shouting. Read enough of them and you see that quite often there is an underlying reason why the reviews are marking a film so low. Be it political or religious. Very rarely is it actually about the quality of the film. More often it is about a personal issue that the reviewer has - and so he vents his anger in the only way that's he knows how - a screaming one star rating and a list of reasons why the film is the worst he has ever seen. Makes you wonder what kind of a strange person would do that.
However, if you read past all the silly 1 star ratings you often get to the truth. And the truth as far as this film is concerned is that it is a cracker. It draws you in like none of the other ape movies - it's pacing is superb, the visual effect stunning.
I would suggest that you ignore the ranting 1 star reviews and take them for what's they are - a few individuals with multiple accounts and strange views on the world.
