Yes you can read flagged comments. Turn on showdead. I leave them off because they're far less often than a regular comment worth the time spent reading.

Oh, didn’t know that, thanks. But still, it’s turned off by default.

Is there a way to improve readability for the downvoted comments?

You could play with CSS, but I'm just selecting these with mouse.
