I have to agree with one of the reviewers here who said: "... the fact remains that John Nettles as Jim Bergerac was and is a surprising success story. I like it and so do millions of others but i feel that no one has really ever explained quite why."
I did like it - how could I not, it has John Nettles. What was interesting to me is that this series made him the European Telly Savalas, but while Bergerac is a good show with beautiful Jersery scenery and Nettles, there isn't anything about its stories or characters that screams "megahit." It's much more low-key than something like Kojack, and his character has no 'who loves ya baby' or lollipops in his mouth, he isn't hard up for cash like Rockford and living in a trailer and dealing with crazy Angel, he's not a brilliant slob like Columbo - If you're expecting some big, flamboyant show, this isn't it.
Throughout the years, the Bergerac character goes through quite a few girlfriends. In the early seasons, he never seemed to like or get along with his ex-father-in-law Charlie Hungerford, portrayed by Terence Alexander. He and his ex-wife Deborah (Deborah Grant) are civil to one another, but then in another season it looked like they might get back together. Later on she and the daughter are basically off the show and Bergerac and his father-in-law are good buddies. Characters come and go, with the regulars being Sean Arnold as Bergerac's boss, Bergerac himself, and Charlie. Later on, Louise Jameson enters as Bergerac's love interest, Susan Young.
I think the secret is Nettles - attractive, with a great voice and a wonderful presence, he was captivating as DCI Barnaby in Midsomer Murders and charming and no-nonsense as Bergerac. He radiates a sexy warmth. I don't know what I was expecting from Bergerac, but when I read it was a huge hit and starred Nettles, I had to see it. I thought to myself, why was this a huge hit? But I kept watching.
