The most authoritative study about the fatality rate of Covid-19 is that of John P A Ioannidis, who looked at the data of a huge number of studies world wide. It's a well known study, and published by the World Health Organisation: https://www.who.int/bulletin/online_first/BLT.20.265892.pdf
. The basic conclusions are all listed in the first page, in easy to read sentences.
When the virus first showed up, it struck quite hard, because there was little immunity. Over time, immunity in the population has built up, this is a natural occurrence; people's bodies are able to resist the virus better now; the fatality figures have come down and are still going down.
So if you want to compare with the flu, it's difficult to make that comparison a fair one. The flu has been around for longer, and there are vaccination programs around it. Still it's a lethal disease for many people. You can compare the flu with a wild animal that we've learnt how to tame but is still making lots of casualties. Then Covid is a new wild animal, it could strike by surprise because it was unknown, but slowly we're taming it. Do you want to compare the flu and Covid-19 both in their tamed form? Then keep comparing the data as they continue to evolve, but it could become a silly comparison in a while, as viruses come and go and perhaps in a while Covid-19 could be all but gone. The Spanish flu went rampant and then disappeared again, and so have lots of other, less lethal viruses. Then Covid-19 could also remain rather dangerous for certain people; it's still now a real threat for very old people.
EDIT: The flu comes back in a different strain every year, but Corona viruses have a habit of disappearing, so this one is likely to disappear at some stage. End of Edit.
I would advise people who want to form an opinion about the virus and what measures to take to gather data, just lots of data. Not individual stories and images, because they can skew the big picture. There's lots of data out there, the virus has been around for almost a year now and has been intensively studied. There are conflicting opinions about strategies, but then it's always good to go back to the data. There are even plenty of graphs that help evaluate the effectiveness of the measures.
