His concern for the house elves, a group he previously mocked Hermione for being so invested in, shows that he has matured to a point where not only is he supporting Hermione's passions, but he's making them a priority. Finally, Ron seems to be mature enough for Hermione.
Instead, they replaced it with a dramatic scene that has the two facing down some sort of water-Voldemort and destroying a part of his soul. Not only is the kiss scene in the book so much more powerful (I'll get to that in a minute), but the film kiss seems less of a declaration of love that's been a longtime coming, and more of a reaction to a terrifying situation.
Ron and Hermione aren't expressing feelings for each other, they're running on adrenaline from destroying a Horcrux and being attacked.
What's so important about the scene in the book is that it recognizes that there has been one major issue standing in the way of the two's happiness for a long time: Ron's immaturity.
In the second half of the series, it was pretty obvious that Ron and Hermione were going to end up together.
What was less obvious was whether or not Ron deserved Hermione.
He was generally immature, was often quick to lash at at her, and rubbed his relationship with Lavender in her face while simultaneously punishing her for her past relationship with Victor Krum. With this scene, however, we finally see Ron begin to grow up. is a long-running point of contention between them, so for Ron to finally, in the midst of chaos, show an unsolicited interest in the plight of Hogwarts's house elves is a huge milestone for their relationship.Upon striking the cup, a giant water monster emerges from the chamber, chasing the two until it finally breaks over them, leaving them unharmed.Looking shocked, the two turn to each other and kiss.It took a lovable-yet-dim Quidditch player for Ron to finally take a bit of notice, and then a bunch of bickering in their sixth year. He was there to defend her honor in the second book.He offered to help her with Buckbeak’s appeal in the Prisoner of Azkaban. But when we really think about their relationship, it was probably a good thing they waited awhile to pair up.
