I quite like the premise of the plot, and remember enjoying it when I first read it many years ago.
I like some of the modern versions of Christie stories, as I read all of them as a child/young woman, and have seen so many adaptations that I always know whodunnit before I start watching. A twist or two makes it worth watching, although some of them have been pretty dire.
This one was ok, I suppose. I'm not much of a 'cozy murder' fan, and this seemed to fit into that genre - a bit like Midsomer Murders or Death in Paradise. That aside, it was ok to watch on an afternoon between Christmas and New Year when I'm not looking for anything too demanding.
I wasn't upset by the so-called 'wokery' - I wouldn't have noticed if there hadn't been so much fuss about it. I just saw the black detective as adding a new dimension and the other references to racism and colonialism as scene setting. There were huge plot holes, I agree, and some of the acting was a bit 'hammy', but that goes with the territory of 'cozy murders'.
I was a bit disappointed with the end. I don't want to spoil it for anyone who hasn't seen it, so will leave that there.
