I don't watch a huge amount of TV, but one programme I regularly watch is Grand Designs. It's never pretentious, always interesting and frequently a great story. Today's show had all of those aspects, made stronger by the tradegy in the opening 5 minutes.
For me, the programme goes to show what a fantastic medium we all work in. It documents the adventure of the house builders, and Kevin McCloud's commentary and insight adds polish to each show. It's one of the shows I watch and wish I had the talent to work in either building, design or video!
