Best and worst acting
Why they make poor Javier angry and walking around mumbling in Spanish during the last couple of episodes is beyond me. It seems ridiculous. I don't blame the actor, just the writing of his character.
I love the acting of Anamaria Marinca as Marta. She seems very relaxed and believable in her role. And Jihae is doing a very good job as twins, Hana and Joon. The remaining actors are just okay to me.
