Not a bad film at all!
This was far better than I'd been led to believe it was here.
The only major storyline criticism was that it was 'only LA' that was suffering, even though there were no media signals, broadcasts or contacts, it would have been a more fleshed out story to have had initial worldwide TV news broadcasts in the early stages (and throughout), rather than just the end shots of London, etc.
It was fantasy, sure, and not the greatest film ever, but it was way better than Independence Day etc?
