Those three films are excellent representations of some of the greatest literature of the English language. They are the only films beside the original Star Wars that I have ever waited in line to see.
I highly recommend watching them on as large a screen as possible.
We have recently started re-watching them. We’ve split them up and are watching each film in two parts (they’re very long).
I agree, they're the only novels I've ever read thru more than once.
