Dracula and Francis Ford Copola's disgrace!

I am a great fan of the original Bram Stoker's Dracula Novel. I believe Coppola's movie is a disgrace to the real novel because it disrespects a lot of major themes in the original novel. Having said that, Stoker's novel never told us why Dracula was moving from Transylvania to England neither did it give us information on how Dracula became a vampire. The only good thing about Coppola's movie is the establishment of a background to the story and this is what he did when he showed us how Vlad The Impaler became Dracula and also by showing us why he was obsessed with going to England (to meet what he believed to be the re-incarnation of his beloved wife who committed suicide).
In reality, Coppola probably got this idea from Vlad's wife who is said to have been a kind and humble wife with a heart of gold. Whenever Vlad took his sword and led his army into battle, his wife's heart grew sad. One night a strange thing happened. An arrow entered through one of the windows of the fortress and put out a candle in their bedroom. Striking a light, she discovered a letter in the point of the arrow which said that the fortress was surrounded by the Turks. Approaching the window she saw many flickering fires in the valley. Thinking that all was lost, and without waiting for her husband's decision, she climbed up on the wall of the fortress and threw herself into the Arges River.
So the suicide part is real in the movie however, as I said, this is all Coppola's idea of how to establish the story and in my opinion, it is the only merit in this movie.
