Hopefully it's the start of a lot more people viewing the handling of the crisis with a critical eye. While people who hate the Tories anyway have been shouting about the death toll, they've been able to brush off most criticism by saying it's unprecedented, we've done our best, wrong to politicise a crisis etc (plus the PR bonus of the Prime Minister heroically battling the virus himself). That's largely worked for them so far.
This weekend though, a big chunk of the country have finally seen what they're really like, and they don't like it. I think they're going to find criticism of they're actual policy harder to shake now.
