I agree that Tom comes over a bit wet. Mind you, so did the saintly late Barbara (still a shame she's gone though.) The actor is perhaps not that good, didn't appear to emote sufficiently at his young wife's death.
It was always a bit odd to me to see Charlotte Ritchie playing St Barbara, as I first saw her in the Channel 4 comedy 'Fresh Meat' playing a much more edgy character. I suppose she got fed up with the role, and by choosing that Barbara died of septicemia *sp? , the scriptwriters have publicised the dangers, which can only be good.
Agree about Dr OneFace, his brother Paul was always a bit of a heartthrob though (those blue eyes!) , and a much better actor.
