I completely agree with your theory! I have read and seen so much I never thought I’d be interested in (let alone love) a couple of years ago.
I’m not a native speaker either - and tbh I have tried to read Shakespeare and I find it really difficult. When I hear it be spoken, it makes a lot more sense to me. I love recorded (audio)plays because I can listen to them a couple of times until I understand the words - although when if it is acted well I often understand the words and their meaning immediately. But then again, I practice a lot nowadays ;)
I love that series! So brilliant. I haven’t had time to watch them all completely yet, so I can’t give you my favourite episode :( You probably know that there is a similar American workshop series, called Working Shakespeare? In case you have nothing planned today :p
