I love Geraldine McEwan, and I have no problems with her as Miss Marple. And yes, Joanna Lumley is inspired as Dolly Bantry. The scripts are well adapted, the acting is good, it should all come together nicely.
I'm afraid I just can't watch these without thinking how it doens't really match up to the standard, set still comparativly recently, by the most amazing Joan Hickson. If you're going to re-make Marple mysteries you either need to wait for the Hickson ones to be *so* old that no-one watches them any more, or even remembers them much, or you need to have something which is not just good, outstandingly and unmistakably better.
And this, sadly, isn' it.
