I mean, honestly, what can I say? This is, to me, a near perfect Christie.
It's a Poirot, which are generally my favorites. Agatha mines her knowledge of exotic travel settings to excellent effect when she sends her characters down the Nile on the Karnak. The personalities are well drawn, and it has an appearance by the enigmatic and intriguing Colonel Race (I'm not going to lie, for me, he is the recurring Christie character with by far the most SA, as Christie herself would've said).
There is a fun little romantic subplot. There are a couple of truly bonkers older women. And the mystery is first rate.
It does get a bit bogged down with all of those extraneous crimes happening around the primary murder, but I don't even care.
