To be clear, I'm referring to https://www.masterclass.com/. I'm not really a professional in any of the fields they offer classes in, and am looking to take it out of curiosity, to get a sense of the different industries (like space exploration, investigative journalism etc). For those who have taken classes, how has your experience been? Is it worth the money and time? Do they come off more as a documentary (I felt the trailers do) or are there clear, useful takeaways?
