Nothing whatsoever to do with Agatha Christie's book, on it's own it's good.

A needless sequel to a great movie (Zombie Island) apart from a few good laughs here and there, there is not much mystery here going around. The villains are boring, the characters keep repeating the same lines for almost half an hour, it could have been a bit more better if it had not tried using the 'Zombie Island' name in it's title !
