For me it was 5/10: solid, entertaining but ultimately badly written. Thus I can answer your question but because of the problematic writing it will raise 10 more (
Lorenzo is divorced, he is a father to two daughters. We can't be 100% sure but later events in the movie suggest that the girls are twins. Lorenzo is also a recovering alcoholic and his interaction with his children is problematic, they do not see each other much. All this makes him easy prey for Sigrid who for some reason is willing to give birth to twins. Lorenzo is given a hint about that but doesn't take it into consideration: the first time he enters the basement laboratory he sees this picture of twins developing simultaneously in the womb.
Later he is not able to see the birth of his child and thus assumes there is just one when in fact there are two. He is also not able to interact with the child on a regular basis, etc., etc. And finally understands that something is wrong seeing that the color of the child's eyes is different.
So there you have it. However, as I said this leads to many more questions. What was Sigrid's ultimate goal? What kind of research was she conducting? Why did she keep the children in the basement? Who was that old woman? Etc.
My guess is that this movie was (in a way) a variation of 'The Boys from Brazil' but not a successful one.
His interaction with his daughters from his first marriage is "problematic" only because their mother moved to Canada with them. He says at one point that he authorised it thinking that he would be able to visit them, but it turned out not to be so easy. That is why he was so opposed to the idea of Sigrid taking Henrik to Norway - because he was afraid she wouldn't come back and he would lose another child.
Sigrid didn't give birth to twins. She kidnapped a different baby so that she could get Lorenzo off her back about not seeing Henrik and not being allowed to spend time with him. The real Henrik, she kept in the basement in a sterile environment, protected from everything and everyone.
Thanks for the reply... Yes, things were not wrapped up in a bow for us all.
Upon thinking about the themes of the movie, one is shown how society is partial towards mothers over fathers. Lorenzo is not taken seriously because he is a man and because of his bohemian background, and thus, injustices are committed against him.
But, like I said, everything is not tied up and wrapped in a bow for us.
Really bugged me that we couldn't understand what Grudum, the midwife, was saying.
=) Thanks for your interest, whalewithhands. Maybe we'll bump into each other on a different forum. Cheers.
p.s.: will put "The Boys from Brazil" on my watchlist.
