I have to agree to new001 - I watched this and while I usually enjoy the series (the earlier ones especially, as pointed out by MandaC), I really couldn't take to this woman at all. Given the fact that she was given a show twice the length of the normal one, I assumed that she was going to give a record-breaking sum for the series.
Though she seemed genuinely touched by some of the stories, you'd have to have a heart of stone not to, she seemed to be very influenced by her Uncle/Cousin saying they were all theives and sob-story-makers.
I felt the mobile school bus was a fantastically worthy cause. I also felt that Toybank was brilliant- she seemed to baulk at the idea that kids be given toys when they should be given food but I think toys are a fundemental part of childhood education and to my untrained eye, while they might not eat particularly well, they were not starving children and seemed truly overjoyed with the (largely cheap) toys they were given.
At the end of the day, she donated £60k of her own money so she has to be applauded for that - it helped people - regardless of the non-altrustic motivation behind it.
