I generally prefer sci-fi to fantasy. A lot of my favorite-ever movies and shows are science fiction. The possibilities of the future and the unknown in space really interest me. I do like there to be some grounding in technical details, but I don’t want that part to dominate. I don’t like all sci-fi, either. For example, I’ve never been into Star Trek. I’ve watched various Trek series and movies, but never go back to any of them. Overall I’m not really into the franchise, and it’s hard to say why exactly, when there are so many other sci-fi shows that I love.
Fantasy has to be really well-done for me to get into, like at the level of Game of Thrones or the LOTR movies. With good acting and writing.
I enjoy historical fiction shows and movies too, and generally don’t mind when they change some of the real-life details. In fact, it can be kind of interesting to look at what exact changes they made. If it gets too far off course, though, then I’ll start to lose interest. Like we watched the first season of The Great but haven’t bothered with the second season, because the show was so ludicrous historically, and I felt like I had already kind of gotten the “joke” or the conceit with the first season, so no real need to go on.
