You hit most of the high points. "A Boy and His Dog" was an early favorite.
I'd add "28 Days Later" as a pretty good zombie style movie. Not exactly end of the world but end of London as we know it.
"The Girl with All the Gifts" and "Children of Men" are well told stories with a different take on the genre.
Skip most of the apocalyptic movies from the late 70's or 80's and especially anything with "barbarians roaming the wastelands" in the plot and especially if it has outlaw/mutant/marauder gangs riding 2 stroke dirt bikes in the 22nd Century. They're not even good for a bad laugh. Except "Road Warrior", that one's great.
Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
