I have just seen the second part of the series. I read the book some time ago so I can compare it to this great story by Lew Tolstoy. What can I say is that the movie lacks the epic size of the story. Historical events were in Tolstoy "War and peace" as important as personal stories which seem to be in this movie the only important. This way the story has turned into a kind of melodrama - just another marital and love stories, without big depth. Most of the characters are not very expressive. I was very surprised of the look of Natasha as I remember her from the book description as very simple, joyful and black haired girl. Prince Bolkonsky is not very interesting and lacks any charisma. I like Pierre Bezuchow and can sympathize with princess Marie. And I can agree: lack of Russian language in any form is very painful. But what can we expect from television drama? Nothing more like the soap opera. And that's it. If I am wrong not having seen yet 3rd and 4th part - apologize.
