hi and i have to say you get some wrong information about the series here . the main author be richard carpenter and he create the series . later on there be some other author but they only do a few episode . the first director who do most of the series ( i think complete series 1 ) be ian sharp who create the distinct look of robin of sherwood . clannad do indeed see some of the material and they read the scrip . i know this for sure because richard carpenter tell it on a con in england last year . i think this be a masterpiece of television entertainment and because it have great character and cast and good costume and great story line . for me still one of the best tv series ever .
