White Wall is an eight-episode Finnish/Swedish tv series from 2020 that showed up on Norwegian tv (NRK1) recently (perhaps it's been there a while and I just didn't know about it) and we finished watching it last week. It is apparently available for viewing on Netflix as well. White Wall is a sci-fi series that I can recommend, although the ending will probably frustrate some people (not me). But I happen to like the sci-fi genre and will cut sci-fi writers/filmmakers some slack if their creations are mostly well-done. I think this series was well-done, even though it moved slowly. It took its time getting to the revelation of what the white wall actually was and what was behind it. Additionally it had an appropriate 'atmosphere' and subtle feeling of impending doom in each episode.
The series has Norwegian actor (Aksel Hennie) in one of the main roles. I thought he did a very good job as the character Lars Ruud, project leader at a former Swedish mining site that is being prepared as a large repository for nuclear waste. There are the extremist environmental activists who are against the opening of the site as well as corporate leadership that doesn't want anything to stand in the way of the formal opening. The underground team working on the site discovers the existence of a white wall at the end of one of the many tunnels after an unexplained explosion. Several members of the team are killed and this prompts an investigation by security; Lars and his team keep the discovery of the white wall secret from corporate leadership while letting the security leader in on the secret. They come to realize that they cannot dig around the wall or excavate it; it has an oblong shape and is quite high. Without giving away the rest of the story, the white wall is eventually shown to be a huge capsule of some sort, composed of carbon and unidentifiable materials not before seen on earth. What this capsule is doing there, who put it there, and what it contains are the subjects of the last three episodes. Subplots include Lars' affair with his colleague Helen Wikberg (played by Vera Vitali), her autistic son Axel's behavioral changes after touching the capsule wall, the activist Astrid and her father Besse (retired but who once worked in the mine and knew about the existence of the white wall), and the relationship of Oskar the security guard with Astrid. The atmosphere is appropriately eerie and claustrophobic, as one might expect when working in deserted mine tunnels. The series was filmed in an actual mine located in Pyhäjärvi, Finland. Kudos to the actors who worked in these mine tunnels for months at a time. You couldn't have paid me enough money to descend so far underground; my claustrophobia would have gotten the better of me.
It's unclear whether there will be a season 2 based on the ending of season 1. Without giving it away, I'll say that it's fairly catastrophic, so what there would be to continue in terms of storyline would be truly challenging to write. But time will tell.
