Let me explain (SPOILERS)

Rating: 6/10 (19 December 2019)

There is no logic in this movie, although the idea is relatively good.
Explonation:
1.two girls took each other places
2. Evil girl went out in the world, good girl went into basement or whatever it is
3.girl was age 10 probably, so has the memories of mom, dad, outside world etc...
4.when she came out of basement, she attacked outside girl (which is evil)
5.outside girl was so shocked and afraid (wait a moment, how come that, when you are a bad girl that organized all of that, now you are scared and don't know what is happening, wtf?
6.a good girl attacks when out, instead of looking for her parents, police, whatever.
7. You hAve to realise that basement girl is actually a good girl, not bad as movie wanted you to think, and outside girl is that evil girl, who acts all movie good girl.
8.finally they explained that down in basement and tunnels live 'that'bad people (i say bad because they were killing their originals in up world), but there is nowhere explonation who create those people, why, what is their purpose, nothing.
9. Ok you watch the movie because of plot twist.
10.actors are really good, but this is kinda artistic movie, so don't expect so much scary scenes, action or something like that.
Enjoy if you can watch after reading spoilers!
