When I see the first few seconds of the advert, I turn off and watch something else. And if I can't seem to change channels, I've been known to turn off the television altogether.
If more people switched off, programmes would lose revenues and the programmers would have to drop those objectionable advertisements altogether.
It's not like I have to sympathise with the "victims" on the screen, because I only see them as actors enhanced with some disturbing CGI.
I know the advert says you should think fast. But people have acted quickly, and it's still not been enough to save their loved ones sometimes. So ads like this should not try and give people false hopes either.
