I went into this not expecting much, however after 20 minutes or so i was lost in this movie. There is so many twists to the story you are constantly on the edge of your seat trying to work out who the killer is. *SPOILER* I was shocked when i learned the vase was the cause of it, yet another amazing twist in this movie.*/SPOILER* Not sure is this was filmed on a set or a real plane, but if it was a set they did an excellent job. The acting was fairly good, there was the odd character that wasn't that good, that being said the movie turned out amazing. If your a fan of horror movies or movies that keep you on the edge of the seat this is for you. I will give this a 9/10
