Badly written. Main characters were never threatened

Rating: 4/10 (18 July 2015)

Spoilers ahead.
The whole movie is badly written. D'Onofrio and Pratt's acting couldn't save this poor attempt at some nostalgia ca$h grabbing. Given the film's budget, the CGI could have been much better. It wasn't bad, don't get me wrong. But it was quite generic.
The dinosaurs were laughable at best, ridiculous most of the time. For a dinosaur movie, there was NO tension at all! The main characters were never in danger. Not even an injury, a bite, a scratch, nothing!
Howard' character is running through mud and stones with a pair of high heels, she never even falls or gets her skirt damaged. The secondary characters' deaths are barely suggested, the camera turning away when the I-Rex bites them. What's the point?
I'm not saying it should be a gore fest a la RAMBO but come on. What about the characters' totally illogical decisions? Let's watch the T-Rex fight the main enemy instead of running away !
What about the Velociraptor that was hit by a car and in the final fight, Deus Ex Machina style arrives just in time to save the day? It could have been a great movie, but there was zero tension.
