It could have been a masterpiece, but overall a very good watch! In the first 20-30 minutes you are going to be upset. Seriously I've never felt so angry, so it is amazing that they could pull out such an emotion out of me trough a movie!! The [young] actors did an amazing and excellent acting job! I was so involved and could feel the raw emotions!! I wish they held longer to this type of filming but they didn't. I wish the 'future' concept would be more different. I thought the movie would have been a masterpiece if the present in the present story that they could focus more on the effects than the plain 'revenge' mode. I wish more emotions would have been involved in this and maybe terrorize the 'bully' on a other way that would be more realistic than this. But if I leave that note out I still thing this movie was very good and it didn't feel like a waste of time. I liked the actors, the music fitted every scene and I would rewatch this movie. Watch this if you like revenge movies with a heavy load of emotional luggage. Skip this if you like light hearted movie with an easy too follow story.
