Maw not sure what you meant by writing Karl Kennedy - Really? Yes, it really was same actor as always, Sadly, he has been stricken by a sudden illness earlier this year that has caused him to lose ALL his body hair (in real life). They covered this with a story line at the time,but he bravely decided to continue in the role to the bitter end
As for the other story lines being tenuous - what on earth do you mean. You admit you have not watched for many years - thougt the scriptwriters did an excellent job, giving all their faithful viewers a good ending AND space for a (maybe) continuation sometime in the future.,
