One thing about the play is that you see the characters. And if the people look different and the costumer doesn’t suck you are less likely to get confused over who is who because you’ve actually seen Lear interact with each of his daughters and you know how he feels about each of them just from the tone & the body language. You also know which brother is which and aren’t going to get confused with which is the good one and which the bad one (they are named Edgar and Edmund. That is not helpful when you are reading. It’s a lot easier if someone has put one of them in blue and the other in red.).
Actually seeing them in physical space will really help you understand what’s going on from a plot standpoint. Actually hearing them (who is yelling, who is whispering, who is pleading, who is sputtering, who is elated, and who is resigned). who is will help you understand what’s going on psychologically. I think you’d be surprised at how much you understand.
It’s summertime - so there are a lot of outdoor Shakespeare productions going on in parks around the country. Macbeth is a pretty popular park play because it’s short and there’s a lot of playing around with swords. You might want to look and see if someone is doing it.
If you can’t see it, I’d suggest finding an audio recording and listening while you read.
I don’t like the “No Fear Shakespeare.” But a lot of people do.
