The Hobbit Trilogy is underrated and on par with the LOTR Trilogy. Peter Jackson & co did a fantastic job of telling the core story of the Hobbit, while also introducing so many new elements. Showing us the White Council and Gandalf’s Investigation of Dol Guldur mentioned in the Return of the King Appendices was a great use of those materials along with a great way to tie the story of The Hobbit closer to LOTR. Jackson & co also did a fantastic job of distinguishing all 13 dwarves from each other and making them unique, something that the novel struggled with.
Also An Unexpected Journey is better than The Two Towers.
