Sequels to well-liked films in this genre usually open bigger and then have shorter legs than the previous film, so the opening points to a lower domestic gross than Star Trek
(unless we see something very unusual unfold, with a sci-fi action sequel that matches the legs of its predecessor). That's not a reason to panic. It'll still hit the numbers it needs to get a sequel. Paramount will be looking to increase appeal to women and the under-25s for the next one.
