Somebody sure watched Planet of the Apes. After already hitting the climax of this Monarch film series which gave us Godzilla versus King Kong, the pair are brought back together to mostly ignore each other in separate storylines, battle each other (briefly), and team-up against a threat that is underwhelming to say the least in a crazy ape and his miniature frost-shooting Godzilla. Other than merging the franchises with something like Pacific Rim or Transformers there was really nowhere for the series to go. And that's where it goes, absolutely nowhere.
The film starts out focusing on the displaced Jia (Kaylee Hottle) and her relationships with Ilene (Rebecca Hall) and Kong who has been searching in vain to find other apes in Hollow Earth. There's nothing we haven't seen before, but these relationships work. That's more than I can say for the rest of the film. We're teased with a warning coming from Hollow Earth. Well, actually, it turns out to be coming from a secret part of Hollow Earth within Hollow Earth.
