While it is certainly different from what you could have expected, I could argue that it is not an entirely satisfying watch. Even though Billie Piper does a remarkable job behind and in front of the camera, the film overall feels like it lacks strenght in the right places. However I won't take away the fact that it takes quite a notable direction in storytelling, which can confuse some viewers, and fascinate others. Obviously this was Miss Piper's intention, but it was not entirely well-executed, in my view. Although the ending did leave me content somehow.
Even so, there are some marvellous performances to behold, such as the one coming from Billie Piper herself, along with Leo Bill, Kerry Fox and the always solid David Thewlis.
Interesting directing debut from Piper, and while not exent from criticism, it is a rightful start that could lead to more precisely elaborated and well-polished endeavours.
