It's a T. rex getting killed by a forced franchise usurper, that's literally it. Only this time it's clearly trying to be done "better", but still, nobody wants to see T. rex lose.
Also gotta be said since I've seen the footage; overall somehow worse than I was expecting in terms of designs, even for some of the new creatures they introduced, so they really overstated the "accuracy" thing and completely undercuts the "nothing in Jurassic World is natural" line/theme of this whole franchise. That said, there is one genuinely on-point creature that I have to actually sing the praises of: the flying not-a-dinosaur Quetzalcoatlus, which is very ironic considering how poorly pterosaurs were represented in the previous films and of course the fact that they are, again, not dinosaurs. Anatomically the only real critiques I have are actually minor -- not minor in a public understanding sense, but like minor to a relative specialist, which is good; that's the place I'd like to be with dinosaur media in general -- specifically the pointy wingtips and oddly long tails, plus the bodies could afford to be smaller (pterosaurs are f-ing weird) but otherwise it's very solid. The way they walk is just so alien, I'm genuinely impressed.
