‘Jurassic World: Dominion’ combines old and new DNA in an XL-sized mediocrity

There’s something unfortunately symbolic about “Jurassic World: Dominion,” which combines old and new DNA from the near-three-decade-old franchise and generates a pretty mindless mess. The nostalgia factor gives the movie an initial jolt, and there are, of course, some dino-sized thrills, but not enough to lift this XL-sized mediocrity out of the gene pool’s shallow end.
