Not that the original series is as spectacularly good as nostalgia seems to have rendered it in the memories of the French, but it definitely has its charm, and some fine acting. It really just IS stage acting on television - the five minute long intro scene of the first episode that consists of all the main characters standing grouped together, and the camera moving from one face to the next while the voiceover introduces them is, well, not something you'd see anymore these days. Or even in those days, on American television.

For that matter, I don't think American television in those days would've had topless women, either.
