"How green was my valley" was the big OSCAR winner in 1942. It's just a flat, strait story telling movie to me, I have no idea how it can beat "Citizen Kane", the same year masterpiece.
However, I do appreciate the scene when that 10 year old sunny boy (Huw) met a beautiful young lady (his future sister in law). It's so pure and beautiful and does carry lots of lively thoughts on its own. That ice cream licking part pushes all the feelings to the top.
