Based on this trailer, I get the feeling of a movie trying to make a compromise between a proper sequel and a sort of remake. And imo, it seems quite risky. Let me explain.
I know we haven't see the movie yet, and even if it's nice to finally see a functional park, it's quite still the same context again. It's ok for the ones who aren't familiar with the franchise, but for an aficionado like me, the new things like tamed raptors or aquatic creatures seems very anecdotic ... I'm sure there will be more, but if the motor of the film is to show that we never learn from our error, we have already see that in "The Lost World" where people tried to make a new park.
I'm not trying to bash a movie based on a trailer, I'm just talking about the promise and what I remember from the director's interview.
If Jurassik Park is a reflection of our world, it could have been interesting to see a metaphore about how today we're dealing with problems related to our impact on the nature... Maybe that was a clue to restart the franchise.
It would have been great to show what the world would become in 20 years of cohabitation with an island full of dinosaurs. Having some migration, presence of specimens on other continent because of poachers, etc, and finally seeing the reemergence of old plants and old diseases.
If you add to climatic problems of our time the destruction of the ecosystem by the dinosaurs, you make a world that becomes increasingly hostile to man, where maybe the dinosaurs seem to fit...
I don't know but if Jurassik Park was about dinosaurs finding their way among humans, a real Jurassik World, to me, has to be about humans trying to find their way among dinosaurs. But I'm not making the movie and I still hope that it will be a good one, even if to me, it seems like an easy sequel for now.
