I have only heard good things about Masterclass and have seen a number of videos on a friends account. It is really good, you learn something but it is also very entertaining and succinct. Teachers include, Samuel L. Jackson, Serena Williams, Neil deGrasse Tyson, Gordan Ramsay, Natalie Portman to name a few. Hope this is useful to someone. If you can split it with someone, comes to $140 each, which I think is very good value.
Extract and review from PC Mag: 'If you drew a Venn diagram showing the best ideas from TED Talks and the high-quality production value from the best television of the past decade, the overlap would be MasterClass. MasterClass is an on-demand learning service in the form of video lectures and demonstrations from the very top talent in many fields. It is simultaneously binge-worthy, educational, and thought-provoking. The quality alone leaves you whispering, "How is this so good?"'
Crikey, they’re expensive.
Must be very good.
