The core and everything in this movie is of course Noomi Rapace - she's doing an incredible job of playing seven different personalities, and doing it brilliantly. Other characters (like the "evil" side) are, unfortunately, not developed at all, but the siblings side is amazing. The plot is somewhat guessable (at least the general outcome), but there's plenty of good action and also a tough and controversial discussion about overpopulation - I'll leave it out of this review, but the thoughts from the movie go quite deep into how society could turn one day. That's also connected to the (small) frustration over the lack of other characters development, there's a rich ground for more elaborate story - but that shouldn't stop you from watching this film, it's very good!
