Very strong and frustrating in my opinion. I do not recommend it at all for teenagers under 16 years of age. Only 18+, and not because of the unnecessary sex scenes, long and above all very frequent in two episodes, that's why I take away one star.
On the other hand, I found the series intense, exciting and interesting. How can you reach this level of manipulation? Incredible but true. The role of Anna, actress Alba August, is well developed, although perhaps they should have used more vulnerability, since she didn't seem like such a stupid girl to me. I don't know if you follow me. The girl friend, who cannot be called that, does not dare to tell her anything about her suspicions, and that is when the drama begins.
Actress Aliette Opheim, Eva in the series, is fantastic in her role as a first-class controlling and manipulative psychopat. Wow..her eyes! And those stares, gave me goosebumps!
I know her from the series Mörkt Hjärta, in which she has a totally different role, a very good actress. I also recommend this other series that I mentioned.
Don't miss it if you like extremely psychological and exciting series!
