It is easy to guess that Abrams was very fond of teenage fiction and with this film paid tribute to all those pictures. There are all sorts of clichés here: a small American town, school summer holidays, some kind of competition, a love triangle, teenage problems, forbidden love, a mysterious creature. All these aspects are present in the film, and here the main question arises: were they specially introduced or Abrams is so mediocre that he can not think of anything other than borrowing. This is a very fine line, but it seems to me that the elements of naivety and stupidity are left as a tribute, a necessary component. This concerns, first of all, a completely stupid scene with a train wreck and the fact that after that the driver survived. This also includes the fact that the alien and his ship were transported on a train and so on.
The small town atmosphere of the late 70s should also be given its due. The house is full of references to every possible horror movie (it's impossible not to notice a Halloween poster), full of references to Romero and zombie movies, it all works, but only the first half of the movie. Further, due to the confusion of what is happening, the atmosphere is also lost.
Acting is certainly not a fountain. Often everything looks extremely staged, the actors replay, or hardly play. The dialogues are written out of hand, the motivation and behavior of the characters are sometimes puzzling.
Towards the end, the film began to be presented as a horror, boo-moments began, which almost immediately began to annoy. You can also say a few words about the alien. Its design is difficult to judge as it appears exclusively in the dark. But it wasn't even that that bothered me, but the fact that, even after killing several dozen people, he was so simply released, they say, the aliens are all good, people are to blame for everything.
It seems to me that this film should be watched according to the mood, not expecting something outstanding and original from it. The best characteristic of this picture is the mini-film, which was filmed by schoolchildren, it is just as naive, childish, atmospheric, with many cliches and references.
