As to your question "has there been a better representation of something like the trilogy (the
books) depicted on film?", I simply haven't seen many adaptations of books to film. The first two "Godfather" films did a pretty good job with Mario Puzo's book. Beyond that I can only recall the film adaptations of Arthur C. Clark's first two books of his "Space Odyssey" tetralogy, "2001" and "2010". My (High) Fantasy reading is practically limited to JRRT, and beyond that my reading (and my private library) is hugely weighted towards non-fiction - as you similarly mentioned about your reading in another thread.
Regarding your question that I selected for my "Reply", I also have doubts, no matter how much "extra" they would have been given.
This has to do with a tendency I (dimly) believe I detect in products for both the large screen and the small, probably a part of the "cookie cutter" and "tick list": that audiences have to be able to "relate" to the characters. That may be fine for sitcoms & soaps & whatever playing in our times. By now it gets tricky if the time period depicted is the post-WW II era up to the 1960's. Go to pre-WW II, perhaps even pre-WW I, then depictions will probably start to ring false. Go back to the 19th century (which in a way only ended in 1914), the we very probably don't know what we're talking about. Go back even further, then it would get more and more difficult to just understand people when they
speak - and regular spelling is also a quite recent development, late 19th century.
No, people who lived in such earlier times - popular periods to depict are the middle
ages, Roman and Greek times, ancient Egypt, anything to do with the Bible - were
not the "reg'lar Joe and Jane from next door", not even remotely. But no, everything, no matter from what period, seems to have to conform to some "modernist" notion - which is why so many critics were and are utterly unable to understand JRRT's writings. No, if the filmmakers believe we must be able to "relate" to most of the characters - with the possible exception of the
Hobbits, but they also belong to an era more than a century ago - they will never get the book onto the screen even halfway faithfully.
