In the 24 hours since its release, the first trailer for Colin Trevorrow's "Jurassic World" has scored a range of reaction. Whilst much of it has been ecstatic about a new chapter in the series finally hitting screens, there has also been expressions of concern. Some aren't warming to the "Deep Blue Sea" meets "Jaws 3D" style story, but much of the criticism is in regards to a handful of the visual effects shots in the trailer and how unfinished some of the CG elements appear. Two shots in particular are scoring much of the criticism - the giant sea creature eating the shark, and more commonly the shot of the train entering the "Jurassic World" gates.
