Hi, I watched the first three or four episodes yesterday of this really interesting documentary on the history of the English language from its very beginning. A lot of fascinating stuff, including being able to hear many of these old pronounciations/versions of English (at least, their assumed ones) and an exposition of multiple vocabulary changes over time.
The only downside is that there are too many vapid filler images/moments that bring nothing of value to the viewer, except make you lose time watching them. I did a lot of fast-forwarding.
