I think they've got a few things right, mostly in the areas of preventing (or trying to prevent) non-pandemic damage to society such as the furlough schemes, mortgage holidays, bans on eviction, sweeping up and housing the homeless. I'm under no illusions that they're doing it for hard-headed business reason rather than the goodness of their hearts.
But doing the right thing for the wrong reasons is still doing the right thing. I don't think they have done too badly at managing the lockdown whilst trying not get to heavy about it.
We haven't had the army on the streets in this country. Yes with hindsight maybe something could have been managed better but they (and Labour would have been in the same position) have been in the position of always reacting to the virus rather than being out in front of it.
And that is where they have failed most abjectly, there was no planning ahead despite us being behind the rest of Europe never mind SE Asia. Opportunities to close borders, stock up on PPE etc were missed when they should have seen them coming, they dithered (not as badly as the US Govt) but definitely there seems to have been a hope it would just go away.
