A missed opportunity

Rating: 6/10 (26 August 2018)

I like this movie but it is flawed.
Most of the movie is fairly boring and nothing happens. Thats the biggest problem. Its just so...... boring...... I didnt want a horror movie, or even a thriller really, but i did expect it to be at least somewhat tense. This movie did not build tension for me. It did not bring out the performance from the actors that it could have.
There are also some problems with the logical consistencies.
For one, It's revealed that the monsters are the adults dressing up as them. This is despite the fact that they make extremely non-human monster noises. I mean the gurgling and clicking and snarling and growling is not a noise a human could make, and even the mentally disabled boy makes it when he dresses up as the monster. I suppose its possible the adults are using secret modern technology to make the noises, but the mentally disabled boy doesnt seem to be capable of doing any of that due to what we have already seen and known about him.
Also about the mentally disabled boy... At multiple points throughout the film, Noah's freedom from rationality is used as an excuse for twists that have no underlying logic of their own.
Second, the big reveal that it is modern day world isnt shocking in the slightest. Its not even creative or original. It just makes you annoyed. The parents (none of them notably religious, mind you) would let their children go blind and die rather than just take a day trip to get some medicine. They could even keep it secret so it cant be explained by them not wanting to reveal the truth to their children. If the point is that they left modern society to protect their children, it makes no sense that they let the boy die in the beginning instead of letting Lucius (or an adult) go get medicine. Thats not very protective, now, is it?
Third, what would happen when the elders die and theres no more monsters?
Fourth, theres no reason for them to speak in the old-timely dialect and idioms. Being hidden away from society, the elders could talk like normal people, its not like the kids could ever know that the way of speaking is that of a modern technologically advanced society as opposed to a historical one. Why would modern people bother to speak in the village's peculiar, archaic idiom? Because if they spoke like modern people it would tip us off. Modern words are not deleted for the kids' benefits, as there is not real benefit to it, but instead deleted for the audience.
Its things like this that make this movie annoying. Shyamalan's need to set up his twists deforms almost everything else in the film. The characters are not speaking to each other, but to us. They are not existing in a logical universe, but one that would deceive an audience.
Fifth, If this is the real world, which it is very much implied it is, what is up with blind Ivy's ability to "see" auras and to make her way through dense woods unaccompanied? These arent things that exist or could happen in the real world.
Its not a bad movie. Its a pretty good movie. But its not NEARLY as good as it could or should have been. It is a missed opportunity. And that makes it infuriating, which really takes a decently good movie and just makes it not worth watching.
