It can be hard to watch and appreciate them this many years later, if you set your expectations based on those who say it, and loved it, at its release time.
That is because, with so many greats you have likely seen a lot of somewhat 'copy cat' material, that while make it not seem as unique, compelling or game changing. A lot of the 'copy cat' material might even 'fix' a lot of the criticisms about the original material, like 'no hero's dying'.
But what i will say, is that when LoTR was released i think it was one of, if not the biggest blockbuster release of that time.
it is probably my GOAT choice for viewing experience, first watch.
