I don't think we can watch the series outside the UK, but I could be wrong.
You will likely find a full spectrum of reviews that range between those that saw wander and those that wonder whether it was worth the time. [I found The Guardian critical of the series, but the author is more liberal arts oriented than one with any science background.]
Perhaps if you point-out some topics that you found informative or surprising, then we can enjoy them.
Or, as often happens, if you found a topic interesting yet still puzzling, then you can present them here for answers.
