I can understand when someone, who has made a
genuine effort to read
LotR, finds it boring. I recall feeling that way at the start, when first reading it at thirteen; but then things began to pick up for me by the time of Gandalf's death, then Boromir's.
I remember particularly enjoying, by the time of
RotK, how everything was coming together, hoping that Minas Tirith would be relieved, and that Frodo and Sam would succeed. That they did with Gollum's intervention amused me. Farmir and Eowyn's romance made me go all mushy.
In short, I was no longer bored.
All this is, of course, my own experience.
