The movie is really worth seeing. Although, the actors in the film are mostly B-class actors that are less familiar with the audience, with only Maggie Q and Lucy Hale being a familiar face known by the audience. However, the cast is quite good, with an impeccable performance , especially how the siblings interact quite well and their personalities are also interesting.
The movie is filmed in the context of the island - the mountains - the resort, so there are many scenes just like playing a virtual reality action game. It feels like playing multiple levels in a fighting game. This is also quite a strange and good thing of the film when putting different situations into a certain context.
