:D This is a lovely post. Saint Joan especially sounds extremely moving. And lol that the only one of these I have watched is (one of) the non-English one :P -- but I will definitely be on the lookout to see if I can watch any of the rest of these; any recs?

I have this translation of Don Carlos by Hilary Collier Sy-Quia, which seems at least much more workable than the free online one, which as you say is not great.
