This may come as a shock to anons who filter their entire existence through video games but literature does not need to operate according to rules of game balance.
Cinema, not literature. In the books the undead army is way less OP than in the movie adaptation. Their only weapon is fear, and they do not liberate minas tirith, but only scare the mercenaries off their black sail ships. Aragon uses the boats to quick travel to minas tirith with his elf and half elven friends and fresh troops from the south.

Their only weapon is fear

Fear and surprise

What about the limitless coffers of Rome?
Fear, surprise, and ruthless efficiency.
Our three weapons are fear, surprise, and ruthless efficiency…and an almost fanatical devotion to the Pope…

Ye I don’t blame Jackson for chainging it, there was less time to explain in the movie and the payoff was bigger. What works in books does not always work in films and vice versa
Jackson’s changes are generally improvements to the story or at worst understandable compromises for a different medium.
