Having read the books and seen the 1982 Anthony Andrews/Jane
Seymour version, I have to say that this is not good at all.
According to the books, Percy is supposed to be a seemingly
foppish aristocrat when he's being Percy, and witty and clever
when he's being the Pimpernel, but here he just looks bored as
Percy and mean as the Pimpernel. Marguerite is supposed to be
the most beautiful woman in Europe, not a tired and frumpy-looking matron (she looks middle-aged, probably due to
bad make-up). Richard E. Grant has done much better things, and
Elizabeth McGovern's acting is uninspired and flat. The wit and
dash of the books and the Andrews/Seymour film is here replaced
by brawn and flashy editing that just don't make the cut.
I might add that to a person who hasn't seen any previous version
or read the book, it would probably look ok.
