rion, you're entitled to your opinion and if you didn't like Puzo's Godfather novel, then I don't think it's fitting for any of us to criticise you for it. One man's manna is another man's mud
If you're a fan of the movies, then GF Returns is probably worth a read. However, you will probably feel the same about this particular adaptation as you did the original novel.
I should imagine there would be a Balkan translation. Have you tried looking on the 'net or in your local bookstore?
