Or is it with me? Well no pun intended and if you have seen previous movies of the director of this, you may see what I did there ... but the joke works without the knowledge too. Now talking of knowing stuff: you should be aware that the main female character has to make a decision about her well being - mentally but also physically.
It is so well played .. and there are so many really good scenes in it. She is broken - she has issues, quite a few of them ... she needs to break free of them (dance the pain away?) ... will she be able to? Because quite a lot of things are being thrown on to her ... she seems like a good soul ... but she is torn inside ... there is more gray (character wise) in this movie than black or white ... it does have questions ... and it is not easy to watch ... but it might stick with you after you watch it ... just be aware what the journey will be like (great performances, awesome sets - which probably are just real locations/houses) ...
