Saw this movie a few hours ago. Insane! It was hectic. The movie was great. The only problems i have is that there is no explanation of the monster and it ends all of a sudden. To anyone seeing this movie in the future, in the last scene where the two people are on the ferris wheel, look into the background to see if something falls into the water...

EDIT: And when the movie ended, the audience got very angry and shouted, etc haha
