Well, I guess Betrayal does change some things to make the ending more in line with the first movie. All apes can be scientists–doctors–but I don’t think there were any chimp doctors in the first movie. I think they were still stooges to the orangutans. Humans are banned from the city. Those two changes about cover it.
Bechko and Hardman establish Zaius as a bad guy at the end, not out of some willful evil but through his embracing of ignorance. Maybe if the comic had been Zaius’s story, how he became corrupt, the ending might have some resonance. But it does not.
There’s a set-up for a sequel, with a gorilla and a human hanging out. Sadly, there’s nowhere for the story to go. The secret ape prison is closed too. Bechko and Hardman are inexplicably reductive.
Great artwork though. Hardman’s art just gets better throughout.
