Ok, i'm a big fan of PBS, and Masterpiece Theater. I started watching a few years ago and got hooked.
Of course i saw "Bertie and Elizabeth", and the "Lost Prince" and thought them both great, though i didn't particulately like the portrayal of the Tsar Nicholas II and Alexandra in the Lost Prince.
Anyways, i think if PBS's masterpiece theater could, they should make a "Nicholas and Alexandra." They wouldn't be concerned about time limits, as their series The Forsyte Saga lasted a good 8 hrs, and my interest in it never waned.
They have a reputation for quality programing, and i really think a new version of Nicholas and Alexandra needs to be made. The old one, well in my opinion isn't that great, and that's being kind. There are some great documentaries out their, but a book and a story like "Nicholas and Alexandra" deserves to be told properly.
