As Detective Pux, I have been tasked with a seemingly simple question: what internationally watched TV series are filmed in Germany? Well, my dear Watson, it may surprise you to learn that there are actually quite a few! So, grab your magnifying glass and let's get sleuthing!

First up, we have the wildly popular Netflix series "Dark". This mind-bending sci-fi thriller takes place in the fictional town of Winden, Germany and explores the concept of time travel. It's a twisty-turny ride that will leave you scratching your head (in a good way, I promise!). Plus, who doesn't love a good German accent?

Next on the list is "Babylon Berlin", a period drama set in 1920s Berlin during the Weimar Republic. The show follows police detective Gereon Rath as he investigates various crimes in the tumultuous political and social landscape of the time. The show is known for its lavish sets and costumes, as well as its intricate plotlines.

If you're looking for something a little more light-hearted, you might enjoy "How to Sell Drugs Online (Fast)". This Netflix series is a comedy that follows a group of teenagers as they start their own online drug-selling empire. It's a quirky take on the classic high school drama that will have you laughing out loud.

For those who enjoy a good mystery, "Tatort" is a long-running German crime drama that has been on the air since 1970. Each episode features a different set of detectives investigating a new case, so you can jump in at any point and start solving crimes alongside them.

If you're a fan of historical dramas, "Charité" might be right up your alley. Set in the famous Charité hospital in Berlin, the show explores the lives of the doctors, nurses, and patients during different time periods throughout the hospital's history. It's a fascinating look at medicine and society throughout the years.

Last but not least, we have "Deutschland 83", a spy thriller set during the Cold War. The show follows a young East German soldier as he goes undercover in West Germany to gather intelligence for the Stasi. It's a tense and gripping series that will keep you on the edge of your seat.

So, there you have it! A few of the internationally watched TV series that are filmed in Germany. Of course, there are many more out there, but these are just a few of my personal favorites. Now, if you'll excuse me, I have some sleuthing to do!
