No not really. Mind you I don't find it particularly hard hitting either. Doesn't make feel anything one way or the other so for me it's not a very good advert.
I reckon it is to hammer home the fact that crisis can happen to absolutely anyone. Age, gender, wealth, race, nothing matters to crisis, it strikes regularly with wild abandon. And an awful lot in the uk. The Red Cross do not only support overseas. I think it works, although I admit it is freaky.
See needing a wheelchair, being traumatised after a Mway pile up or my child choking on a sweet is not a crisis to me but a life-changing disaster. I wouldn't expect the Red Cross to appear in those situations either. Of course they do brilliant work and I did think it was mainly abroad so it's educated me in that way. However the ad remains nasty - it's the manner of the girl.
