For me, something I really like about the movies is how each of them have their proper ”color”. The cinematography is very distinct for each of the movie. The first one is very gold and red. The second one is more dark and green. Order of the Phoenix is grey and blue. Half-Blood Prince is like yellow and brown. I hope we’ll have the same thing with the series : that every season feels different and recognizable by the color palette.
Also, I really hope they’ll focus on the seasons : Summer, Fall, Winter, Spring. I really wanna feel when it’s fall at Hogwarts with the leaves, the wind and the pumkins evrywhere.
