Overall, I love Long Lost Family.
HOWEVER, I watched the UK version first and the US version is a bit of a let down.
The UK version shows respect!!! If the parent has died, they tell the child AWAY from the cameras. The US version chooses to show the despair with the cameras fixated on the poor child's face. They also say "We've found your Mother!!" The child says excitedly, "REALLY?!!!" Yeah but, she's dead!!!
Poor form.
Another episode shows a brother/sister meeting for the first time and the hosts interrupt them to say "We've found your father" to the son. This poor half-sister was not related and she just has to sit there.
All the show had to do was show respect to these poor people who have searched for their family for DECADES.
Maybe I'm biased because the UK version does it perfectly but, the UK version was made first and the US version CHOSE to take this path.
