I did see that one recently - I was glad I knew about the changes advance but I did think it was fairly well done given all that, my main issue was that it ended up being a bit of a visual strain to watch for me as the version on Amazon Prime was colourised in an odd way (I'm not sure why as I have since discovered other places that have it available where it's in normal black and white which would have been fine).
I have since watched the 1980 version of WDTAE, which is a big improvement over the Marple one but I'm still partial to the new one - hopefully you don't have more technical issues when you get to the rest.
