We all pretty much agree that Rons character in the films got sort of nerfed. Key character moments were given to Hermione and they made him a tad one dimensional.

As a result it feels like the book Ron is not really realized on the screen in all his glory.

I think this is at least partially because Rupert Grint had such comedic chops in the first film. He is hilarious. And I think seems a good bit ahead of the other two in screen presence, skill and timing early on. I think it was directors and writers instincts to lean into that and make him the comedic foil on screen. By the time the 4th film rolls around the pattern is set. Hermione gets the smart parts, Ron gets the jokes.
