I tend to agree that the spinosaurus was created for the purpose of a bio weapon, because it wasn't on the list that was given to the federal government after the second film incident with the T. Rex in San Francisco. They could have done this type of thing for twenty years with no one the wiser, at least until the field test in the park. Of course, I don't think the hybrid Rex was a smart idea on their part as it just created a genetic killing machine. The original Rex was bad ass and I liked the part were the heroine of the film does the iconic Dr grant pose to lure the original T. rex that was just pure baddass moment right there.
Unfortunately, we, the consumer, are to blame for it as well. As Owen said in the movie, "They're dinosaurs, that's 'wow' enough.", but the people end up growing pretty bored to them, even the carnivores, because they're "common" now when the fact is, even 22 years after the first movie, the fact that we have dinosaurs, even if not completely genuine, creatures that were extinct for over 65 million years walking around among us would still be a huge deal. That boredom is what lead to profits not being as high as before which leads to them trying to create the I-Rex in order to spike attendance and bring in more money again (though, unknowingly playing into InGen's hands as the I-Rex itself was also essentially a prototype for further bio-weapon creation).
And people like Dr. Wu are exactly the types that Malcolm described in the first movie - "Yes, yes, but your scientists were so preoccupied in whether or not they could, they didn't stop to think if they should." He clearly is one of those scientists who doesn't really care about the consequences or morals of his actions so long as the science is progressed while people like him and corporate bigwigs only see the dinosaurs as "assets" or like giant action figures rather than living, breathing animals that require respect, like Sattler also said, "...but these are aggressive, living creatures that have no idea what century they're in, and they'll defend themselves, violently, if necessary".
Ingen create bio Dino weapon in some remote island, and some mistake happen that release all the Dino from facilities and killing everyone.
My question is, will it go family friendly or not?
There was a big hurricane that was about to hit Isla Sorna that required evacuation of all the staff and everything (Hammond even calling it a possible "act of God", like punishment for what they did and were still doing), so they simply released all the dinosaurs that were already created and held there while evacuating, assuming that the dinosaurs would simply die from the hurricane itself or at least within a week due to lack of Lysine - If they weren't artificially supplied with it by the staff, they would go into a coma and die after six to seven days (a contingency if any dinosaurs were to escape either Isla Nublar or Isla Sorna), but the dinosaurs, first the herbivores, circumvent it by eating plants on the island that have a lot of Lysine, then it gets "passed on" to the predators when they eat the herbivores that eat such things.
