Man Fahrenheit 451 is my favorite sci-fi book.
science ficition  often explors potential conseuqences of scienctific and other innovations. its called the literature of ideas. while i liked F451 my favorite sci fi right now has to be black mirror
Black Mirror is good too. I was watching some yesterday, no joke!
yeah. sci fi typically avoids the supernatural unlike fantasy. ilike with both genre combine though!
Sci-fi and fantasy are really similar aren't they?
well in the past sci fi had grounding in actual science, so you would take actualscientific theories and expand on them. they were not fantasy like, it had to be based mostly if not all in science. but now thats only expected of hard science fiction. now the genres of fantasy and sci fi are intertwined more than ever!
Wow, that makes sense. I kind of like the old feeling of sci-fi.
i can see how you feel about the genre though as it is difficult to define and includes a range of subgenres and themes so. the lines to sort of blur.  
I liked the old feeling of sci-fi because there was a sense of horror that it could actually happen in our world.
i totally understand that.like  scientific dystopia genres. whereas with more fantasy it feels more distant andunbelievable.
