I mean I've read and watched a lot of fantasy and I think fantasy is largely all garbage piles so maybe it's just not the genre for you.
To be fair fantasy is a lot easier to pull off (and in turn a lot easier to screw up). I know a lot of fantasy works just come down to the whole "it's magic I ain't gotta explain shit" cliché.
Well I'm sure the law of averages suggest that most genres are filled with mediocre works.
But I think you're correct (Kuro). In that, I think the "explaining everything" bit is part of it. Because both of them rely on suspension of disbelief, using largely unbelievable/unlikely concepts. So when Fantasy says "magic and emotion", cliché as it might be, its a lot easier to buy. Versus when not smart people attempt to make up bullshit science jargon on the fly. Because its both so much closer to reality/therefore far less believable.
Also, fantasy is and has been far more broad in its use in media, generally speaking. Where as, a whole lot of scifi shows, do a lot of the very same things. I'm sure if I found some comics or something less soap opera-y. (Got a lot of scifi hand-me-downs from my parents.) I'd find the western Steins:Gate.
But I have to keep trying. If you don't try something based on usual taste, you'll miss the best stuff of its kind.
