Agreed! I liked Disaster in the Burbs partly because it focussed on a divorced woman (though also Christian, no premarital sex, blah blah) and I'm sure there was one with a Mexican couple living in a trailer
In general, not great characterisation, and while I don't have a problem with guns, reading pages and pages of numerals listing this, that and the other just makes me want to scroll right by, when I have no idea what they're on about (though I know that Noah Wyle, in his Steven Spielberg tv series, uses 50cal a lot
so I recognise that) but all very samey, yes
Thinking of *free* fiction - check out if the kindle book "Arisen" is still on offer on kindle - its a 12 book series, and I ended up with about 8 of them, free for 48 hours or so. Zombies, alpha teams, v v military and then goes all existential by book 7 or so.
With some hunting, you can find amazingly good apoca fic written in the universes of various tv shows. I won't link because there's a *lot* of very steamy same-sex male pairings, and this stuff is mostly written by women for women. Search out Stargate apoca fic or fanfic, stuff like that, or include a character's name as well.
