"Boring" is pretty subjective. I am sure there are people who think the series is boring. I am sure there are people who think books are boring. There are people who find puzzles boring and there are people who find Facebook boring and there are people that find boxing boring. Nobody can tell you what you might find boring.
What I can tell you:
It is a VAST and extremely detail-oriented series. Tolkien achieved one of the most thorough and exhaustive fantasy universes ever; the books are classics. Does that mean spending quite a bit of time reading details about histories and characters and places and nations and cities and events and cultures (etc. etc.) that have little or no relation to the immediate plot? Yes. Is that boring? For some. For some it is delightful.
My personal experience: no, they were far from boring. You know what I did think was boring? The Silmarillion. It was brutal, and even for a strong (at the time) high school reader, it was difficult to follow.
Recommendation: Read The Hobbit first; it is less demanding. If you find The Hobbit difficult to get through, don't bother reading the trilogy. Watch the movies again instead. They are phenomenal, and you will not have to deal with the struggle trilogy-readers face of constantly telling your weary friends "But they didn't include _____ !"
Cheers
