The writing is intelligent with a slow build up but heating up at the finish. The Scottish shooting locations take your breath away as does the final scene which they would have had to get right the first time as there is only one Edward Woodward.
It complements the original classic well – the casting is spot on with Everett & Firth, who are vanity free, excellent. You get the impression from the "making of" that everyone enjoyed making it with the female cast having a ball. Watch the music video
The first half of the screenplay sets up the relationship between the characters whilst the second packs a political punch. At all times the characters are believable, the pacing is just right and the dramatics are justified.
It is all a bit too romantically commercial at the expense of the more serious things that were happening at the time but that is not to say it is not worth a look as the production values are excellent.
