True but it was a... movie... made for entertainment value --and as a nice side effect captured the imagination of millions of children (as well as adults&#x27;).  So, yeah ,they got known details wrong and in retrospect, as we currently understand, got further things wrong... But again, it was a &quot;blockbuster&quot; movie, not a high brow film or a scientific study.  Thus, I don&#x27;t have anything against how they portrayed the beasts.  I think it&#x27;s understood they took visual license and incorporated sci-fi.
