Just back from seeing Fallen Kingdom and I really enjoyed it. It was like a philosophical sequel to the original Jurassic Park in sense that it illustrates how "life will find a way" more than just more dinosaurs escaping from cages like the last three sequels. It pushes the message of how chaos stems from humans harassing the power of genetic creation.
There were some dumb scenes, and silly character actions, but overall I thought it worked well. One complaint is that there seemed to be less chemistry between Pratt and BDH's characters than there was in Jurassic World, oddly. The cinematography was a lot better than JW's but there was little use of the classic score. A lot of tasteful nods to the original. It was done right and fit with the theme.
I feel like this is the first JP sequel that actually moves the overall story forward rather than repeat it.
