Good Craig got his c'nuppins
The first trailer is brilliant.There's still quite a bit of dinosaur action. And compare it with the trailer for the 3D re-release.
As @Nickosaur says, it's more a problem with modern trailers, but I actually think the first trailer (for World) did it quite well. The dialogue was hammy, but it was still intriguing, whilst holding enough back.
Anyway I'll try reserve judgement on the Jurassic World trailer 'til I see the movie. Could be a different story altogether.
