Kenneth Branagh's Vision of Frankenstein

Kenneth Branagh's 1994 adaptation of the novel Frankenstein - entitled Mary Shelley's Frankenstein - claims to be true to the original text. But is this the case?

Obviously, the movie takes liberties with the storyline on many levels. So how true to the vision of Shelley do you feel this movie is? Does it match the book on some levels but not others? Does it capture the mood and tone? The plot? The setting? The characterization? On what levels does it remain true to the artistic vision of Shelley?

As you answer, consider specific differences - such as Walton's reaching out to the monster in the end, the creation of the second monster, the use of Elizabeth for the second monster, the similar appearance of Victor and Walton, etc. Look for these and other differences and explain what the movie makers both gain and lose by making these changes.
