The people who made Jurassic World apparently didn't realise that audiences don't care about hybrid dinosaurs - normal dinosaurs are super interesting enough. So, yes, it's a bit of a shame that the filmmakers have gone down this route, especially since it appears as though the "hybrid" in question is going to be a combination of both T-Rex and velociraptor, based on the brief footage of those giant, fast stomping feet. It also seems a bit silly, given that the people in charge of Jurassic World must have taken stupid pills if they're messing around with hybrids. Would that really happen, given all the stuff that went on in the previous movies? Doesn't a hybrid plot seems a little... forced? Whatever: it's not going to ruin the movie or anything, but it's a bit anti-climatic to discover that this is the plotline that the filmmakers decided to go with.
