I am honestly not surprise at the ending. Fans who went to give presents to Michael saw the brothers with a camera crew not long ago. They also concluded it was for the show, which made some of them fairly said.
I have no problem with the brothers visiting their brother and they said some sweet things. However, even though I was not emotional about the whole thing, I thought it boarders on bad taste. They could had done it without the camera and I honestly cannot see why they did it. For me, visiting someone is a private moment and not one that should be taken lightly or shared with just anyone. I think Michael would agree.
However, I will not blast them too hard. It is not like they took pictures and sold them to the media like another certain person did. They also never actually showed his grave, most likely because Forest Lawn wouldn't allow it.
In either case, I don't care what they did in the end, but it could had been worst.
