[Requiem]

Of the ones mentioned, I think Lord of the Rings was the better trillogy. Star wars is no longer what I consider a trillogy, and most other 'trillogies' I can think of do not come up to that particular scale. Of course, Trillogy here I only refer to movies in sets of 3, there are many other movie 'legacies' out there that I would think of as better.
