A series of indifferently staged PG-13 set pieces, brief appeals to the international market, and heavy doses of foreshadowing for the already announced sequels. (Is there a mid-credit teaser, you ask? Yes, of course there's a mid-credit teaser.) The momentum is further stymied by actors who seem vaguely grouchy and out-of-sorts. Equaling Linda Hamilton is no easy task, but Emilia Clarke, who's terrific on Game of Thrones, comes across here as a cosplayer on the last day of a convention. by Andrew Wright
