The last couple seemed to want to try to do more with the philosophical question of cloning and gene editing beyond dinosaurs, and the practical implications of dinosaurs reintegrating into the global ecosystem, but was unwilling to follow through on either.
I haven't seen it yet but the new one is yet another soft reboot that re-restricts things to an island, and the only things I've really seen about it is that it doesn't actually follow through on the base promo concept of the trials and errors of cloning, and that it doesn't really have a raison d'etre beyond an excuse to adapt the raft scene from the original book (I think that was the last leftover setpiece from the original book).
