In one sense a typically built alien scenario, invaders and some rebellious characters at school introduced in a very typical way for when this movie was shot, and some nods to classic horror flicks as well as some interesting monsters, i enjoyed the dialog suggesting that science fiction writers are writing partly from fact, which brings into question, what do we really know about reality itself, who we are, except the film was more focused on thrills n' chills. everything is strange from the beginning, until you gradually realize the truth. Interesting movie.
