Well, the reaction of Colin Trevorrow himself can be read here.

I had initial mixed feelings too. However, if it is done properly, the D. rex plot can be really cool AND scientifically possible. The Cuttlefish DNA was probably only used to make the D. rex poisonous. Poisonous dinosaurs have been part of JP ever since.

Jurassic Park films and book have featured lots of dinosaurs that had characteristics of other animals. T. rex frog vision, Dilo's frill and poison-spit, Carnotaurs chameleon skin etc. I think it is better to say openly such a creature is a engineered hybrid than pretending it is the real animal. If you didn't left the first film after seeing the Spitter, you will survive the D. rex.
