Finally I saw this movie and it's hopeless. It is supposed to be based on the book, I heard. Well, half of the movie is not to be found in the book. At some point it became so ridiculous I was actually laughing.
The only good thing in this failure is Robert De Niro, who was very touching as the 'monster'. His performance was very close to the book. He gives the 'monster' a heart, as it should be.
Otherwise, don't bother seeing this thing. It's a waste of time and not worth the title of Mary Shelly's Frankenstein. This is actually Kenneth Brannagh's Frankenstein.
