I don't usually write reviews but this episode struck me so hard that I feel compelled to share my thoughts, even if I am just echoing much what many others have already said. This episode is intense, unflinching, uncompromising, almost overwhelming. It took me most of 15 minutes to realize I'd become perched literally on the edge of my seat, so involved and invested in what was happening that my surroundings had faded away. Suddenly, I realized that I'd been watching one continuous shot. (In fact the entire episode is comprised of just a handful of long, sweeping, dizzying shots). I absolutely love the use of long shots in film and TV. They're technically impressive, allow the actors (and characters) to flex and shine, and they suck you into the story in a way that jump cuts (and jump scares) never will, and they make it hard to look away as the tension just builds and builds. The cinematography, and choreography, in this episode, are stunning. The acting is top-notch. Not only do the adult actors do a fantastic job, but the child actors are mind-bogglingly good. Throughout this entire series, I've been highly impressed by these talented young people. I look forward to their long and illustrious careers following the amazing work they've done here. I'm not going to do the thing where you describe the episode in detail as you review it (though, I'm very glad many of you write reviews that way, they're a pleasure to read and often help me appreciate aspects of the episodes I missed the first time around). I just wanted to give my impressions of the episode as a whole. I know some people found the first few episodes to drag a bit, and it is definitely a slow burn, but the whole series finds a feverish peak here. Everyone involved with this episode, on and off-screen, is at the top of their game. Do yourself a favor, watch this series if for no other reason than to get to this episode. Watch it, watch it again, read some reviews, descriptions, and the IMDB trivia page, of course, and then watch it again. It keeps on giving; this is one of those shows that gets better with every viewing, it opens up and flowers into something incredible before your eyes. Favorite episode by far of one of my favorite series in recent years. 10/10.
