Honestly this is the kind of movies I dread the most, UFO and extraterrestrial beings are by far the perfect match to prevent me from sleeping, but this one is unoriginal and the aliens don't scare anyone.
In my opinion there are some patterns in alien movies you have to follow, just like zombies or ghosts but it isn't these patterns that make your movie unoriginal but the way you mix them up and put them into action to make sense the whole movie. What it bothered me the most was the fact the characters didn't seem frightened enough, I mean, you don't have any idea what you are dealing with, you're supposed to be scared and desperate but their faces showed otherwise (except for Emily Perkins) and don't get me wrong, the acting was good but could have been better. Plus I didn't like the fact they were acting like superheroes, they were just kids but decided to fight them and I don't know, that's something I didn't like about movie.
Despite all I've said the movie is good if you want to pass the time, it has action, it is interesting at times and has good effects and the ending is quite surprising.
It's up to you to decide if you want to watch this movie, it's not bad but it isn't a masterpiece either, a five star movie definitely.
