It's funny as hell people using Jurassic World of all movies to prop up against Avatar. People sure like their dinosaurs. Fake-ass "dinosaurs" in this movie's case, anyway.
No doubt. When you think about James Cameron, first thing that comes to mind is "Man, that James Cameron sure is pretentious."
And you're totally right. Colin Trevorrow, an absolute nobody, crafts and executes action sequences better than the pretentious douche responsible for Aliens, Terminator, Terminator 2 and True Lies. That Colin Trevorrow, what a genius, that guy. He will user a new era of cinematic revolution, I say. A Pre and Post-Trevorrow age, if you will.
