This. I can't believe there are so many people saying you'll love it just because they did.
If you didn't like The Hobbit...I doubt you'll like LOTR just because it's longer and deeper. I personally don't think it has a lot of character development. Not compared to a lot of more modern work. I think it's very unfair and shortsighted to tell someone to go read a book because you loved it, especially when they've clearly said they didn't like the prequel...

IMO, The Hobbit is a fun adventure, but the last 1/4 is dull AF. I can't belive kids want to hear about all the rebuilding of the town and crap....

The LOTR is a good read. I'm not into fantasy, but I enjoyed it. But it's not for everyone. And the Hobbit is a good litmus test.
