I've been watching a lot of old TV lately. Really struck by the fact that Lew Grade / ITC threw stupid amounts of money at The Persuaders! with its glamorous stars, filming locations, it has the best theme tune of any TV series ever (John Barry) - and yet I find it unwatchably boring. By comparison, I love the low-budget, shonky, grimy Randall and Hopkirk (Deceased) that came before it. (Which also has a top-notch theme tune by Virgina Astley's dad Edwin.)
