1976's 5 BP noms included 4 dramas that could be seen as "downers" to some degree and a feel-good underdog story.
Probably not a shock the last one won!
4 of the 5 are very good or great movies. Only "Bound for Glory" seems meh to me...
I agree "Shape" didn't deserve the win, but disagree with "Billboards" was better - it left me cold.
"Lady Bird" was my pick from 2017, and I'd have taken "Dunkirk" or "Get Out" as well...
