There are serious logistical flaws. For example, The Lion, The Witch, and The Wardrobe occurs during WWII in the 1940s. Peter, Susan, Ed, and Lucy Pevensie flee London for the country because London is being bombed by Nazis. This is a huge plot point and shapes how the characters interact for the rest of the story. It is impossible for Digory to have lived in the 1950s, because he built the wardrobe which Lucy climbed into. It’s made out of Narnian wood, which is why it becomes a portal between two worlds. Digory grows up to be the eccentric professor who the Pevensie children take shelter with during WWII. The era change completely upends the entire series. I don’t understand how anyone familiar with the source material could make this kind of mistake.
