A sequel was inevitable after the first part ended up narratively unconcluded and with critical acclaim, so the story picks up right where it cut off, with Emily Blunt still trying to keep her children safe in a hostile world where no sound goes unpunished. Nothing new is introduced, however, apart from Cillian Murphy's bereaved, reluctant ally, so it's really just a game of avoiding the aimless monsters, which are still given no motive or rationale, only relying on their presence as a means of forcing the human protagonists to cope with each other. This results in some emapathetic small dialogues as well as a constant sense of tension when the danger simply can't be planned for, but can't get any further than some vague War of the Worlds-type get-out clause. The franchise has duly reached the end of its natural lifespan, no matter how much anyone might still see bucks to be made by carrying on.
