Yep, believe Dark is indeed a German movie. Until you know who's who, within each timeline, it can be quite confusing. (And a bit repetitive) ... But I actually watched it twice over the last year or so. (Been throwing some stuff on just while hanging about the house) So thought I might keep up better? ...Not.
Think I've seen Tenet advertised, but haven't watched it yet. I've been finding just the odd series here and there on Netflix, and find I enjoy them more for simply not knowing all the players. I get tired of seeing the same folks just playing different roles, where they pretty much still appear to be the same characters, just different movies. - I've also watched the Mandalorian series on DisneyPlus, as well as Black Widow. But haven't checked out the Boba Fett one yet. Did watch the Falcon/Winter Soldier one a while back though.
Finding flicks from other countries has been nice, and to be honest, they don't have to be great for me to enjoy. Just being different overall helps a lot. ... It's how/why I watched "The Rain", "Black Summer", "Glitch", just to name a few. Oh, as well as "Squid Games", which I actually avoided for quite some time before actually deciding to watch it. So once done, I ended up starting another Korean series with a lot of the same folks, "The Silent Sea" and lastly just started watching "The Haunting of Bly Manor" (Think I have two episodes left on that one?)
