I've not read the LOTR for a long while. I read them first when I was 8 (my teacher failed to believe I could understand them at that age and used to quiz me on the plot), and for while I'd read them yearly. Can't have read them in, 8 years or so now. They're not for everyone, I had a crack at picking them up again and couldn't bring myself to enjoy the slow pace another time, and they are painfully slow in parts. I can sympathise with anyone who doesn't get on with them.
The films, despite (probably wisely, on reflection) not following the books nature as less action more travel, do suffer from that decision imo. I bought the extended editions on Bluray this year, watched them all back to back one weekend, and the fact that they want to be (and largely are) just action flicks means that the slow bits with Frodo are really pretty dull. He's not a terribly interesting character and he's so limp and so little happens that each time they appear on screen from the second film on it just feels like they're a buffer for the next big fight with Aragorn and the like.
The books focus being on the journey more than what actually goes on on that journey makes that problem less apparent. When Aragorn and co are swashbuckling theres little said about it, it's not written heart racingly, whereas Frodo and Sam are more intrinsically tied to the story of a journey, so they aren't quite so dull as they are in the film.
Thats an issue the Hobbit doesn't have. They barely get going before they're tripping over cantankerous trolls, tricky spiders, goblins and dirty great talking wolves. And at the end they play a dangerous game with a cunning and evil dragon and end up in a war. They might go on a journey but it's effectively the party falling from one bit of action to another.
