Haha... probably not.
I just had this crazy idea that either Dr. Alan Grant (Sam Neil) or Dr. Ian Malcom (Jeff Goldblum) would make a
cameo, post credits. The movie ends and then there is a bar, the TV showing the news of the incident, camera zooms out and that iconic shirt+safari hat sitting on a stool watching it. Camera then pans up on him and it's Dr. Alan Grant... "They never learn do they *sips drink*" <blank screen> credits continue to roll.

(or swap Dr. Alan with Dr. Ian).
Yes, absolutely. I was initially not really in favor of a hybrid dinosaur, felt like everything was ruined at that point. It is like an 'insult' to what made the JP movies what they were - - actual dinosaurs from fossil records.
But... they managed to capture the spirit of the original (JP1 in particular) as you said and that's what made Jurassic World worth watching. It was very respectful to the originals films.
Even with the hybird dinosaur + raptor training, they managed to keep it 'grounded in reality'. Totally believable.
Hey who knows... if there are Raptors around today, they could just be trainable.

(and why not... parrots can be trained and birds do share the same 'evolutionary' lineage as dinosaurs).
As for the park, indeed we
never got to see a working park with visitors. Jurassic World delivered that, and it's a first for the JP movies. The film makers/screenwriters must have had one of their main priority to have a functioning park (at last).
Might catch this again next weekend, just for fun.
Agree man, the hybrid fit in well with theme of the movie.
If they went ahead without the story of the hybrid, ppl will complain that they just remake the 1993 with a modern twist without anything new.
In the end, they show the fossil dino rock the show.
