Jurassic world movie run time?

Hey guys just wanted to bring something up which id like your opinions on

The trailer tells a super fast version of the story but only the new open park side and not the past stuff. 

Think they have to fit a build up in and y they Actually go to the island.

Tys mum in the trailer say. "Im so proud of you for going on this trip" now if i was a kid i wouldnt need persuading to go id be there in a shot , like most of u lot. Now her saying this tells me that maybe the man in the pic is not their dad or it is and they r going because of bad family time qt home and she sends thr kids away to get away from it alL so her and the bloke can sort it out? Anyway Just something i noticed ????

my next thing is the movie timing. Now for any back plot about this has gotta be very early on. There is a lot of stuff that needs to be put in before they even leave for the island.

Not even to mention :

The history of whats happened in the past 20 years,

the old ruins the new park, then the actual visit We whitness.

While this is happening we have a sub plot of what we believe is the d-rex,

then we have to experience everything the kids are seeing around the park.

And thats even before the  nasty shit all starts happening! There is so much this film needs include

Its gotta  be at least 2 and a half hours long! There is so many dinosaurs to see. I dont want to just see the same ones i want the other dinos to get screen time atleat whilst the kids roam in the gyrosphere And that we WANT to see. Thats my one and only worry! I have full faith in this film and colin will deliver the best film of th franchise. But that is my only worry. Pratt said from half hour in ppl start getting eaten. Thats not long time frame to cram in what i just stated. Wht u guys think ???!!

im solely enthusiatic aswell i love everything portrayed in thr trailer it was sick ! Just enlightening ppl to sometjing im worried about. 

Maybe a part 1-2 and 3 and we just aint getting told?
