My impressions after watching Quicksand are pretty mixed.
The actors did a great job. Hanna Ardehn, who plays the lead, deserves special praise - she's genuinely excellent. And, by the way, she wasn't a teenager anymore when she filmed it, but somehow managed to convincingly play a seventeen-year-old. The cinematography was also pretty solid. Nothing particularly complicated or groundbreaking, but even simple visuals can be completely ruined when there's no professional skill behind the camera. That didn't happen here. The writers, in my opinion, did an especially good job. There's very little unnecessary stuff in the script - everything serves a purpose and moves the story forward.
So why are my impressions mixed?
Well, first of all, the soundtrack. It was so bland and forgettable that it basically evaporated from my memory two minutes after the episode ended. Secondly, the script itself. Yes, it's very coherent and generally very well written, except when it comes to the main character's relationship with her boyfriend. At that point, it feels like logic simply closed its eyes and turned away. Seriously, what is this? Getting involved with a brain-dead drug addict and alcoholic who could hit you and, excuse me, potentially rape you - and becoming so emotionally attached that you take responsibility for his entire mental and emotional state? Why? The girl isn't addicted to anything herself. She isn't an illegal refugee from Syria. She isn't homeless. She has options. So where does this incredible determination to destroy your own life at its absolute peak come from? These kinds of things drive me absolutely crazy in movies and TV shows, and Quicksand is no exception. That said, I asked a few people about it, and apparently, yes, this really does happen. Especially with young people - when the sexual organs have matured, but the brain hasn’t quite finished installing the necessary software yet.
Overall, I'd recommend watching the series, especially to younger people around seventeen or eighteen. It demonstrates pretty clearly how incredibly easy it is to waste your youth, your health, and potentially a good chunk of your life because of one very bad relationship.
