I have never read an Agatha Christie novel. I do not think this counts as a moral failing. Particularly because I just haven’t read that much out of the mystery section in the first place, you know? It is my understanding, however, that she is kind of a big deal.
So she has this one character, Hercule Poirot, who is a great detective. Possibly the second character ever to be bestowed with that title in the annals of fiction? And although I never thought about it before Kenneth Branagh’s performance, I guess it must be true that all detectives in the Holmes / Poirot type, who can become (or possibly always are) hyperfocused on specific details and make deductive leaps based on the tiniest shreds of evidence, all such detectives fall somewhere pretty deep into the spectrum.
So, while not knowing the plot meant that I showed up for Death on the Nile to be interested in the details of the murder[s], who did what to whom and when and why, what I left with was a renewed respect for Branagh’s craft, portraying someone who felt very deeply while hating to feel anything at all. It was very subtle, and very moving because of how subtle it was, and I’m sad I missed his Murder on the Orient Express from a few years ago. I shall perhaps eventually do something about that.
 What does perhaps count as a moral failing is that what I have read is mostly chosen based on “I liked the TV show they made later.” …then again, if I started reading Christie, it would be because I liked this movie, so.
 at least in part because, how much have I thought about this character at all, sure
