I watched it because the big guy from Game of Thrones makes an appearance (he’s even on the poster of the version that I watched), but he’s only a bit character in a story that goes much deeper than I was expecting, examining who our loved ones really are in comparison to what we think they are, and how we react to unthinkable situations.
It’s a good film, which is being remade in english, due to be released in just a couple weeks. I didn’t know that going in, but it’s a cool coincidence.
