This epiosde is again a very solid episode, not particularly outstanding but also not a failure. The atmosphere that is almost reminiscent of The Descent in some places really creates a great tension. In addition, much is also left to the imagination of the viewer, so that much remains open to interpretation. But even if the episode has quite interesting approaches, not much is really brought out of it. The episode is definitely entertaining, but it is not really remembered, as it is quite generic.
However, the animation looks fantastic again as usual. So you can't complain about it and in addition, the cold and gloomy pictures also create a great atmosphere during the episode. Above all, however, the small details that were really well staged in the lighting and presentation are remarkable.
So overall, the episode looks really good and has some interesting ideas why the episode is also worth a look, but it doesn't really have much added value.
