I’m coming to the end of the series, and I too got the same impression: that there’d be more episodes. I think we should be told !!
Also, I thought there’d be more history about the individual countries in S America: Bolivia, Chile, Colombia, Venezuela etc and their history: from indigenous populations, through Hispanisation, rebellion, early leaders (Simon de Bolivar, etc), economic success (Cuba, Venezuela, Argentina) then economic failure with Chavezism and Peronism, etc.
Maybe a bit too much stuff for 10 episodes !
Would be an interesting follow-up course though, I think.
