There could be several reasons. Maybe you find the science and technology elements overwhelming or confusing. Or the storylines might seem too far-fetched for your taste. It's also possible that you haven't found the right science fiction work that matches your preferences.
It could be that the often complex and futuristic settings in science fiction make it hard for you to relate to. Also, if the characters and their development don't engage you, that could be a reason. Sometimes, the special effects or technology-focused aspects might not appeal to your interests.
Maybe it's because the themes or concepts in science fiction don't resonate with you. Or perhaps the way it's presented just doesn't click for you.
The reason why they disliked science fiction was probably because such novels usually contained a lot of scientific elements, but they often did not conform to one's understanding and imagination of the real world. Perhaps it was because science fiction was often too sci-fi and did not match one's personal life experience and perspective. However, if you liked science fiction, you might like those that explored the future and technology.
A lot of people don't like science fiction because they think it's too focused on future or alternate realities and not enough on the present. Also, the genre can sometimes seem too technical or nerdy for their taste.
Hard science fiction just doesn't appeal to me. Maybe it's because it requires a lot of concentration to understand all the scientific theories in it. I like fiction that I can relax and enjoy without having to think too hard about science.
Hard science fiction often focuses too much on complex scientific concepts and technical details. It can be difficult to understand and lacks the emotional and character - driven aspects that I enjoy in other genres.

It's unlikely. Dune is deeply rooted in science fiction concepts and world-building. Without a fondness for the genre, you might find it hard to get into the story and its elements.

It could be that you haven't had that one amazing fictional story that really grabs your attention. Sometimes, it's just a matter of not having come across the right one yet. Also, maybe the way fiction is presented to you doesn't appeal to your style of learning or entertainment.
Maybe you've been exposed to too much of the same kind of fiction and got bored. Or perhaps your interests have shifted to other things.
