The trailer for "Jurassic World" debuted during the Super Bowl on Sunday and finally introduced the world to the new "hybrid dinosaur" set to scare moviegoers this summer. Not everybody was impressed, however.

Indominus Rex, made of T-Rex, velociraptor, snake and cuttlefish DNA, confirmed his "worst fears," Troy L. Smith said, The Cleveland Plain Dealer reported.

"The hybrid looks about as ridiculous as the CGI'd Spinosaurus from 'Jurassic Park III,'" the critic wrote. "I think everyone would have been content with a simple, cool-looking Tyrannosaurus Rex."

HitFix, meanwhile, voiced some doubts about the plausibility of the science behind I-Rex and the mental well-being of the fictional scientists who created the monster. The new raptor was "concocted from a Tyrannosaurus base, with a mixture of other deadly carnivores shoved in," the website said.

"There's a dash of Carnotaurus, a hint of Madagascan hunter Majungasaurus, and a sprinkling of Rugops. And because that wasn't terrifying enough, they topped it off with a dollop of Giganotosaurus, a predator second only in size to Spinosaurus," HitFix explained.

"Jurassic World," the fourth installment in the "Jurassic Park" series, is set to hit U.S. movie theaters on June 12. The $150 million production was directed by Colin Trevorrow and stars Chris Pratt, Bryce Dallas Howard and Vincent D'Onofrio.

The Super Bowl trailer also showed how Pratt -- a "Jurassic Park" on-site staff member -- interacts with the raptors, Fashion & Style noted. The publication praised the way "Jurassic World" shows its reverence toward the original "Jurassic Park."

"At one point we see (Pratt) and (Bryce Dallas Howard) tending to a sick dinosaur, much the way (Laura Dern) does in the first film," Fashion & Style detailed. "Then, at the end of the trailer, the I-Rex goes after Zach and Gray while they're in the Gyrosphere, and we get a shot of them on their backs, staring up at the dino in terror -- just like Tim and Lex in 'Jurassic Park.'"

For those who want to learn more about I-Rex, a piece of concept art is available on the official movie website, Design & Trend revealed: "[The raptor] is said to have a very high aggression index and to be bigger, louder and to have more teeth -- all the better to terrorize unsuspecting visitors to the park when things eventually go haywire."
