You can say you couldn't get into the movies.. but don't be an elitist and say "the machine is why people like them" because that's just wrong and attention-seeking.
There's a reason the books are beloved and so popular.. there's a reason the movies did incredibly well at the box office and are well-reviewed.. because they're that good. Not because it's "cool" to like it or anything like that... but because they're high quality.
And to be honest, people who have these kind of hard opinions on movies rarely give them a fair shake. If you went to see them in the theaters without any preconceived notions, your opinion would flat-out be different. But instead, you heard how great the movies were and everyone's high praise and expectations.. then you watched it on TV and probably on TNT with commercials
and you probably wanted to dislike it just to go against the grain. It's not your fault if you didn't see them earlier, but it absolutely affects opinion if all you hear is how great a movie is and it doesn't live up to that
expectation. Whereas if you just saw them on your own, you might rank them a solid 7/10, but when you expected a 10/10.. you're going to be disappointed and unfairly judge.
Don't compare them to Avatar... they're not even on the same level. No one praises Avatar as a great overall movie with tremendous acting and nuanced performances.. it's purely a spectacle on a visual level and it does such a great job of that it overcomes the other weakness. And I can maybe understand if you're not into the fantasy genre, but this isn't like Tarantino or Wes Anderson or a very specific kind of film/style where you're either a fan or you're not.. LOTR is universal enough despite dealing with magic and orcs and what not.
LOTR is just an incredible trilogy of movies top to bottom... and I'm not even a fan of the series like that, but I still respect it. And despite how much one might dislike a movie, you have to give it your full attention and actually finish the movie. I know plenty of people who say things like "I couldn't get into it, I was playing with my phone the whole time"
cut the distractions and give a movie a fair shot.
