I really love the story, and I think the young girl who portrayed Ana Lucía is exceptionally talented. In the series, she has a very warm personality, emotional, a very positive vibe. But when she grows up, her vibe is suddenly cold and distant? Even though she's been through a lot, the story doesn't make her cold and distant, so I feel like the adult actress just had the wrong vibe for the part. She also looks nothing like the little girl. Absolutely nothing. They have very different facial features, and they don't even look like they could be related. Such a huge difference. There has to be SOME resemblance for this to be credible. This bothered me throughout the whole series. Besides her, casting was on point. The actress should've been a different character. Someone mentioned here that her age was wrong for this character, too, and I agree. If they had cast someone who fit better, this would've been an amazing show. I'm convinced the young actress is going to be very successful though! She's a natural. The kids in the first part were very good. Young and old Mejía (In reality son and father) were cast perfectly as well. Same goes for Toto and Dorita.
