I think the three Peter Jackson Lord of the Rings films were very good adaptations of the books as well, even though they deviated at times in very material ways from the source material. The artistic and practical choices Jackson and his team made for the film adaptions to me not only made logical sense, but also just worked very well to make good movies.
I would essentially agree, but there's one thing still I can't get over with: that they didn't include one of the most iconic, important and very much cinematographic moments of the battle for Gondor, the Nazgul Witchking entering the gates of Gondor and finding Gandalf atop Shadowfax to face him.
It's beautifully written in the book, and would have really translated perfectly on screen. The gate that was never breached by any kind of enemy comes down, torn by Grond, the battering ram. Every soldier loses hope, they all run away in fear, and the Witchking enters the gate... and there's Gandalf on top of Shadowfax standing alone before the Nazgul, telling him to piss off. And in that moment of absolute despair, Rohan finally arrives.
In the film they instead chose to botch it by showing random CGI creatures breaching the gate, and the very brief confrontation between Gandalf and the Witchking is delegated to a cut scene. I'm still annoyed at that.
On the other hand, the first of many examples of scenes masterfully done is Gandalf with the Barlog. I perfectly knew what was going to happen, and yet I was hoping that Gandalf would have made it.
