What I found particularly irksome about this particular programme was that it was assumed almost from the outset that the children had been abandoned, based on pretty flimsy evidence, and when the story unravelled it turned out that this was not the case at all, but of course it made a much better story when told that way. I'm not sure that any self-respecting genealogist would have jumped to such dire conclusions based on so little evidence !
And, of course Sam Womack didn't really have to travel to the USA to find out what she needed to know - it could all have been done by email, but then we wouldn't have found out what colour the front door of number 36
1/2 was

And I suspect that Ms Womack wouldn't have agreed to do the programme without an expenses-paid trip to the US?
My grandfather's brother emigrated to the US, and I've managed to find out all about his family, have located many living relatives, and have located photographs of the family, all without travelling to the USA. If anyone over there had offered me a free ticket over and free board and lodgings, I probably would not have turned them down
