Alright, I'm gonna recommend the youtube channels
Bedtime Stories and
Unclassified Encounter
Bedtime Stories deals in the bizarre, the strange and the frightening, from ghostly hauntings and UFO encounters, but also mysterious deaths and grisely crimes all told in a chilly atmosphere with some amazing artwork. Really solid work.
Unclassified Encounter is a newer spin-off channel, where the subject are short stories, usually set against a backdrop of WWII, where soldiers have run-ins with the supernatural and the unexplained. They're all bangers so far.
If you enjoy solid documentary and theme parks, or children's television, I can not possibly recommend
Defunctland enough! The started by simply retelling the story of former attractions at Disney and Universal, then went on to full parks (the Action Park one is worth the watch) and then also branched out into nostalgic TV and did this absolutely amazing mini-series on the life and career of Jim Henson that left me in tears at the end, and a full length (90 min) documentary on Disneyland's forgotten sci-fi band. Just quality content all around.
In the same vein, on the children's television side, the channel
Poparena has been doing an amazingly deep dive into the History of the Nickelodeon TV network with the 'Nick Knack' series. It goes over all of their major productions, and many of their important acquisitions, one by one in chronological order and goes into the show's history and the people behind it. It's SUPER fascinating and very well researched, with the author mentioning his sources at the end. I'm not American, so a bunch of these shows I've never watched or even never heard of, but I really enjoy the documentaries nonetheless. They also have a fun series, Monthly Goosebump, that goes over every book in the series one by one.
I feel like this one might be too famous but what the heck:
Jelle's Marble Runs! For years now, Jelle's, with the help of commentator Greg Woods, has been entertaining the masses with his amazing marble races! The sand rally, the Marble League (former Marblelympics) and Marbula-1, all with every-increasing production value and their own dedicated fanbase. (#MomoStrong) It might seem silly at first, but I big you to watch
Marble League 2021 to see what it's all about! Who knew you could care so much about inanimate balls?
