I only like my own apocalypse

Snowpiercer and These Final Hours continue apocalyptic film tradition - The Final Cut - ABC Radio National 

 I've noticed some ad or something for These Final Hours, which is an Australian "we've only got hours til the end of the world" film, but I knew nothing of its story.  In the article above, we get a description, and the mechanism for the end of the world sounds unscientific.  (The film sounds violent and unpleasant too.)

Why can't global disaster movies get the disaster scientifically plausible?   The only one which I think really did try fairly hard in that respect was Deep Impact (and I thought it a pretty good film generally.)

But so many are just utter rubbish with the science - that shlock German director's The Day After Tomorrow and 2012 (hey, we're still here),  the (awful other) "asteroid hits Earth" movie Armageddon; even World War Z, although I was surprised to enjoy its video game similarities, had a ridiculously brief viral zombification scenario.  [And, I might add, it annoyed me continually that the wife kept making satellite phone calls from the inside of the navy ship she was on.  Surely you'd have to be near or on the deck for that?]

In fact, generally speaking, I can't say I like apocalypse films as a genre much at all.  I'm not sure why I'm supposed to enjoy ones with bleak, hopeless endings, even if they do manage to get the science vaguely right.

Which is all a bit odd, perhaps, given that I was recently talking about my own apocalyptic thoughts whenever I'm driving out in the Lockyer Valley.  (And, incidentally, I wrote that post before hearing about These Final Hours.) The thing is, I like my own apocalypses, but rarely anyone else's.
