Undeniably, this film frequently crosses that fine line separating the ridiculous from the unbelievable. But then! What else could you reasonably expect from a faithful adaptation of Shelley's gothic nightmare? There is no way anyone could have turned this into a Ken Loach film.
As far as I am concerned, this is a globally OK version, perhaps because the novel excels more in the field of action than in that of stylistic acumen. (Being deprived of the text, therefore, is no great loss.)
