It seems that from the land of the living dead, the speed of the zombies has begun to increase. I remember reaching the peak in a certain zombie movie, and the zombies began to learn to think and attack in an organized manner. The zombies in this film also belong to the evolutionary type. While increasing the biting force, they also increase their speed. Efficiency is an effective way to increase their strength.
To my credit, the hero's personal heroism on the roof of the car reminds me of the finale of my favorite movie "Perfume: A Murderer's Tale," which, coincidentally, is all French. The director put romantic drama and sadism on zombie films, which is also a kind of freshness and surprise.
As for the sudden change in Scar's mentality, and that last shot, I can only say that she is a typical dual personality.
