I'd like this film to have more action from the herbivores. Like, have a scene where the humans are being chased by carnivores and get caught b/w a herd of Triceratops or Stegosaurs (or w/e) and the herbivores get defensive and end up protecting not only themselves, but the humans indirectly.
And a Spinosaurus vs. T.Rex fight done with a King Kong face-off would be nice. Like in the previews for the film, the V-Rex roars at Ann, then Kong jumps down and roars. I'd like to see Spino confront the humans, then Rex comes out from behind and roars at her. Then we get a jaw-to-jaw fight. Not some silly 10 second spin around like in JP 3.
