It's a fun Agatha Christie adaptation, with a few more unexpected twists and turns than usual and also more bloody than we're used to.
If you're into whodunnit films and like Hercule Poirot explaining to everyone why they could be the killer, before assembling the whole cast and revealing his mental gymnastics to them, then have at it. I like that stuff, even though it's always the same kind of thing, naturally. By no means special, but a nice comfortable viewing experience still.
Also, why do people keep murdering when Poirot is around? Fools!
