I might see how the younger generation might stir up comparisons, between the two franchises, but it seems like apples and oranges to me.
I have nothing against LOTR, I think Jackson did a solid job on these movies, but I was completely disinterested and bored and actually started falling asleep a couple times.
Star Wars completely absorbed me, when I saw it in 77, any comparisons are a fan thing, Star Wars changed the way movies were made and the industry itself....a little different than a film adaptation of novels that use technology that Lucas helped set the standard for.
