Watched King Lear last night. Sadly I found it disappointing.
I think anybody coming to the play for the first time would have been extremely confused, since it was drastically cut, and many links which would have made sense of the (pretty bizarre) plot were left out. I hadn't watched the play before or read it, so this applied to me.
What did come through with the very fine cast was the magnificence of Shakespeare's language, and here I was pleased to note how many phrases from the play were already familiar to me.
I don't think the updated setting added too much, since the inevitable anachronisms were very glaring, and attempts to find modern equivalents unconvincing.
