They’re neither depressing nor the opposite
They provide the best available evidence (often with heavy caveats that it’s an evolving picture which may change)
They lay out what is going on. You can choose not to see this as depressing. Indeed it might even be better to make a deliberate effort to see it as neutral - and further than that, the point from which we can see a way ahead
Because this lockdown has massively reduced transmission, even including the new more catching variants. They are right to say that we need to get it even lower, and we need the hospitals to empty out before restrictions can change, but they are telling us that we are getting there
They’ve been consistent, evidence-based and non-political throughout (they point out what is the scientific remit, and that it is the politicians who make the policy decisions).
And it’s a good thing that the evidence is so readily available - it’s been one of the things that has stopped the response being used as a party political issue.
