It definitely requires the right frame of mind. I love it, but I’ve never really met anyone else who even likes it.
“Dystopian” fiction. The world is still functioning more or less. But in a way that seems disturbing and bizarre to us. Still very enjoyable. I would include Ninteen Eighty Four, Brazil, Total Recall, Johnny Mnemonic, The Island, and Babylon AD in that genre (although not all those films are of equal quality).
For post apocalyptic TV series, you have Jeremiah and Jericho.

Are you thinking of Cloverfield?
Ok, here’s what we seem to have so far in the genre of pre-, during- and post-apocalyptic films, leaving out (near as I can tell) those that are more ‘dystopian future’ flicks:

A lot of great suggestions for future viewing; thanks.
Whoops, forgot Zombieland.
I can’t BELIEVE no one’s mentioned Dr. Strangelove
If Escape from New York counts, certainly Escape from LA does.
Some more that come to mind:
*Dawns Early Light
Red Dawn *
Not post-apocalyptic, The movie ends at the apocalypse.
That’s not really an apocalypse film either, just a war movie.
Fail Safe – ok, a two city apocalypse
The Bedford Incident (if you believe the nuke at the end was the first shot of WWIII)
Invasion of the Body Snatchers
War of the Worlds
Battlestar Galactica?
Silent Running
The Blood of Heroes
Malevil
The Time Machine
The OPs last list includes, pre-, during, and post-apocalypse movies/
IMO Red Dawn is one of the Signs of the Apocalypse. 
Certainly it concerns the destruction of large partts of society.
No, I am pretty sure they (msmith 537, that is) are thinking of Last Night (indie, L.A., vague apocalyptic event approaching, Sandra Oh). What’s funny is that the first person to quote the person that you (Hung Mung)just quoted actually mentioned Last Night by name–but they didn’t quote the part of msmith’s post that you just quoted; just the part about Miracle Mile and something else, so I guess they didn’t even notice that they were talking about the film that msmith 537 couldn’t remember the name of.
Whew. Did that make any sense at all? I would have just left it alone, but I was all peeved because Miracle Mile and Last Night were the 2 I was gonna mention.
Fox once tried to do an actual sitcom about four or five people living together after a nuclear holocaust. It was about as putrid as you’d expect. All I remember is the last line of the first (and probably last) episode: ‘Great. The last tube of toothpaste in the whole world, and some idiot had to squeeze it from the middle.’
This, I remember. High school French? Gone, gone,
I think Last Night is set in Toronto, or some other god forsaken Canadian city. 
BTW, was there ever an explanation for how everyone knew the world was going to end?
Okay, I misspoke when I said “Death Race 2000”. I meant to say “Deathsport”, which was the sequel to “Death Race 2000”.
AFAIK there’s no legit video or DVD version, and it’s not quite post-apoc, but the ABC miniseries AMERIKA. Kris Kristofferson is released from the gulag in Soviet Amerika & treks cross-country to raise popular resistance. Meanwhile, Sam Neill- having failed in his stint as the AntiChrist- becomes Commisar.
Great premise, made in response to a challenge by Ben Stein, mediocre execution.
And a homage to Dr. Gene Scott at the end.
Anyone else see this?
I remember my older sisters watching it, but I wasn’t too interested at the time.
Woops!, which itself was a parody of a post-apocalyptic film, possibly The Day the World Ended (1955).
Another avant garde effort is Peter Greenaway’s The Falls. It’s a very odd duck indeed.
I only know it because SNL did a parody of it called “AmeriDa” where the US is taken over by Canada.
That’s the one.
I don’t think they ever gave an explanation. It had to be something foreseeable but not preventable, so I’m guessing an asteroid or something.
Now I want to see this show.
