From reading the synopsis on this movie I was quite looking forward to seeing it but I can't express how disappointed I was. There was no storyline, the relationship between Michael Fassbender and Carey Mulligan as brother and sister was completely unrealistic (e.g. He walks into the bathroom whilst she's in the shower and she doesn't rush to grab a towel to cover her modesty?!). There was nothing likeable about the characters and nothing interesting happened at all.
If you like "artsy" films where the scenery is pretty and the camera work is good then this is the film for you. If you like a decent storyline and a character you care about then it most definitely is not.
