My problems with Science Fiction and Fantasy books

I love science fiction and fantasy, don't think that I have a problem with them, I love immersing myself in Tamriel and Middle Earth, the ideas of weapons and beings beyond our imaginations makes me giddy. The problems I have aren't with the genre itself, it's mainly with the writers and the readers. Allow me to explain.
1. Taking themselves to seriously 
So I couldn't get into science fiction or fantasy in middle school, because they tend to recommend incredibly serious, heavy stuff. It was quite a switch from Wishbone and Animorphs.

Tell me a time where being a starfish would help you save the world.

In fact, if it wasn't for Douglas Adams, I might have never gotten into the sci fi/fantasy realm past supernatural love triangles.(Another time maybe). And I'm not saying that all science fiction needs to be as delightfully random as Douglas Adams, I'm saying that there needs to be more authors like Adams and Robert Asprin. There needs to be more options for those who want a light-hearted, but not kiddy, science fiction/fantasy to read. 

2. Where are the women writers?

I know, you can't blame the famous male authors for doing well. And I'm not, I love Tolkien, Asprin, Adams, Moore (even if some don't say his stuff is Sci fi, but I think if you read Fluke you'd call it Sci fi) Millar, and I'm starting to read some Alan Dean Foster. And I know there are women writers in both of these genres, but a good amount are young adult novels and the others I haven't heard of. And I'd be willing to try some of the young adult novels if it wasn't for the force of the love triangle. I was told about The Hunger Games a while a go, but I couldn't bring myself to read it. Not that it didn't have an interesting idea, but the back of the book made the love triangle front and center instead of a side note.

Screw political commentary, Peeta and Katniss forever. 

3. Re-used tropes 

Games have slowly been getting better at this but Douglas Adams and Christopher Moore are offenders of this. The Damsel in distress and/or sexpot. And my favorite in fighting, they either tend to be hyper-masculinized or hyper feminized. And I'm not even getting started on fantasy armor. That started out in books and it hasn't ended yet.

Look all in all, I love the sci-fi/ fantasy genre. Just the books are sometimes not very female friendly.
