Why do they keep insisting on mutants?

I was really excited about the Jurassic World Rebirth trailer until I got to the end of the trailer and saw a mutant monster. Does anyone actually like that?

Well, I just HATE the concept of mutant dinosaurs, bizarre monsters that barely look like dinosaurs. They were animals like any other, but they were products of their time. I love how the first three movies have dinosaurs that are dinosaurs. Okay, I know there's always been the concept of modifications, like them changing sex to reproduce, after all they are lab-made dinosaurs and not 100% original. But even so, things like what we saw in the World trilogy make me really upset about the movie, I hate these mutant dinosaurs that look like they came out of an Alien movie or something like that.

Eddit: 1 I think some people didn't understand, I'm not complaining about them not being dinosaurs. I know they're not ACTUALLY dinosaurs, I said that up there. What I'm complaining about is that I'd rather see a terror around a Carcharodontosaurus or Allosaurus than a Rancor from Star Wars

Eddit 2: Should have used monsters instead of mutants in the title
