There's a big difference between a Star Wars saga trilogy and a Jurassic trilogy. We have every reason to believe the Episode IX will follow the same trend as previous Star Wars trilogy closers and come up significantly above the middle act, closer to the first film in the trilogy. We have no reason to believe the same case will hold for Jurassic World 3. I mean, we literally have precedence to look at in either case.Yeah I mean, not to bring up Star Wars yet again, but if Fallen Kingdom's performance is worrying for Universal, I would have to think TLJ and Solo would be downright panic inducing for Disney / Lucasfilm (and I don't think they are or should be)
Solo's non-comparable to Jurassic because it's a spin-off and had entirely different context, but even then it's not like LFL is just going to ignore what happened with that film.
I'm not saying Universal is running around with their head cut off right now, but given all of the context specific to the franchise and Universal as a whole right now, I see no reason to believe it's unreasonable to state Universal isn't particularly thrilled with the outcome at the moment, and is at least considering making some change ups (specifically in the creative department - I'm increasingly of the mind that Trevorrow's days are numbered unless Spielberg pulls for him HARD. He was already fired from Star Wars by the wife of Jurassic's producer).
