Boris Johnson's sombre tone reflects the fearful, uncertain mood of the nation.
To that extent, his speech will likely be judged a success.
As ever, Number 10 is acutely aware of the latest polling and public sentiment.
But despite the top billing and days of hype, this address does the absolute minimum it could.
And it doesn't really begin to answer any of the difficult questions facing the country, though he creates a fair few new ones for himself.
Indeed it is so minimal on current and future changes that it prompts the question of whether, even just a few days ago, the speech was meant to be a bigger deal than tonight it has become.
It does not even mention garden centres, which government sources on Friday said would reopen on Wednesday.

Also it does seem to have been the subject of last-minute revisions: cabinet papers on additional detailed changes put on ice in the last 48 hours.
And Tory MPs who were furious with the headline change – to ditch the "stay at home" slogan and replace it with "stay alert" – were told the address was a "work in progress" even today.
Things changing, it seems, at the last minute. Parts were recorded yesterday, parts today.
The biggest message from the prime minister is that those who cannot work from home should go out to work.
Hearing this from Mr Johnson may have a big effect on manufacturing and construction.
Yet this is not even a change of policy – that has been the consistent position from the beginning, with ministers making it clear from the Commons at the start that builders should go to work.
That tells us that Number 10 views slogans like "stay at home" as more important than policy or law, meaning tonight's minimalist speech could have a more significant impact than they intend.
The combination change to allow more exercise a day and to sunbathing is more significant than it seems or that he spells out.
This is intended to signal that people who want to sit next to one friend on a park bench, albeit at a two-metre distance, will be able to. Why Mr Johnson couldn't spell this out more clearly isn't obvious.
