I’ve just rewatched to see if I can see anything menacing it it and I really can’t.
Son looks anxious, dad looks confused then happy. It’s intense but not “dark”.
I think the way some posters have seen it explains a lot about all the weird posts on here where people don’t seem to be able to relate to people or communicate- they see bad in everyone and can’t read body language at all.
It made me blub more the second time actually.
