In movie terms, without appreciating the drama and amazing screen adaption of the emotions of the near end of the world (!), RotK was the worst of the three. From a plain movie goer's stance, one who is just seeing the movie for things like the Battle of Pellenor fields, there was nothing "new". A great battle like Minas Tirith, they already had Helm's Deep, a giant spider? How many movies have had giant spiders? 50? Then there were walking and talking trees in tTT! But, someone who appreciates the masterpiece of the movie, the Two Towers was the best. Followed by Return of the King then the Fellowship of the Ring. FotR is last because I always think the Shire names, cultures, etc. are kind of stupid. But it was still a good movie but a better book because it needs Tom Bombadil!
