Hmmm....I love both the movies, and also both the soundtracks were moving..
I think that you can't say which movie is better. If you want to see the whole story i'd say 'Nicholas and Alexandra', even with the innacuracies it has, but then again 'Romanovy' shows them as a family and really tells the story of their last months and is allot more acurate on the sets, and I think that both movies did a good job on the looks of the actors in general, only the girls in 'Nicholas and Alexandra'didn't look like the girls at all, which was a bit annoying...
