I love Only Fools And Horses, although anyone could see it should have ended on the trilogy, bringing them back was just tragic.
But I really really adored it when Grandad was in it. No offence to Buster Merryfield as the uncle but Len Pearce was just sublime, and totally believable in the role, whereas the uncle always felt tagged on so they would have someone else in the flat to bounce off and do the leads to the jokes.
Len's timing was a joy, from that great line about the bullet hitting his father's watch and blowing his brains out, to well, there are just so many. He was very integral to the charm of the original show. Having said that, they did go onto to make more rounded episodes later on, when it was allowed to grow and add pathos. But I always missed Grandad. Bless him.
