Good movie. I consider Veronica to be a superior film, but this is how you make a prequel. Completely different on its approach, with significance for the original story, yet very much its own thing.
Very good performance in the lead role by Aria Bedmar, whom I wasn't familiar with, but who showed a range of nuances in approaching this character. I loved the production design and cinematography, with Paco Plaza once again demonstrating his exceptional camera work, one of the best in the horror genre, and always maintaining impeccable mise en scene. Once again, sound - mixing, score and sountrack - is also a standout in his works. I can't say it was scary or terrifying, but it's a very well-paced story, creepy enough, and with some very interesting setpieces.
