I think a major problem with Jurassic World isn't so much that there was "nothing new" so much as what new stuff there is on offer isn't good even on the relatively simple level at which a movie like this is supposed to operate.
A major point of contention was that this was the first Jurassic movie to actually kill off a female character, which had the result of making her get what might just be the most drawn-out and absurdly brutal death in the series
(which is thrown into even sharper relief by the fact that the genuinely despicable human villain dies a swift off-screen death, whereas the worst this woman does is lose track of some kids for an instant).
I wasn't bothered by the off-screen death of Hoskins. I think lingering on him would've interrupted the pace of that sequence. In any case, he never struck me as being the film's real "villain" anyway. He's despicable, sure, but the villain to me was always the Indominus, which killed things because it liked killing things.
Though really if you want to put blame on the a human character, then you should be lamenting the fact that the truly despicable one in this story - Dr. Wu - keeps surviving and creating more monstrosities despite having seen the tragic consequences.
The attempts to offer empty replications of old characters (e.g. the two kids) not only function as empty call-backs (as do the various references to the old park)

But don't even offer any interesting variations to make them into decent characters even by the relatively low standards of the previous films. The kids' parents are getting a divorce? Who cares. The down-and-dirty raptor guy has tension-laced banter with the uptight female executive? Groundbreaking.

I'm positing that it's hard to care about effects-driven spectacle in a vacuum. It'd be one thing if these characters were just flat, but their treatment within the film goes past flat and into bad, which makes it hard to care about who lives or dies (even the most genuinely tragic death in the film has multiple asterisks attached to it).
There's got to be at least a little worthwhile substance in place and Jurassic World - a film that takes easy pot shots at bland corporate products even though it is one - is so lacking in it that even the effects do little to paper over the gaping cracks.
