Why does Hollywood end movies featuring modern dinosaurs with disasters?
This and Son of Kong both end with mini apocalypses that really feel out of joint with the narratives. Skull Island and Caspak (only referred to as Caprona in the movie) are fascinating worlds that deserve better than the Apocalypse.
Yes, I'm aware The People That Time Forgot revisits Caspak, but most of the charm is lost in the resulting film.
Oh, well.
At least Caspak lives on as a rich, fascinating world in ERB's original novel.
Requiescat in pace, Krystle Papile. I'll always miss you.
