....well, it suffers from a dearth of ape-men but...will the target audience get the Kubrick reference, or are the people who made the film being 'meta'? If the target audience isn't little kids then who is it?

How does smashing the old-fashioned dolls result in an all-new doll-inhabited world of 80's fitness freaks? Why is Barbie a giant in that first part? Why am I even asking these questions?

Because the teaser works… yet, as you questioned, for whom? I stand by my original thought: strange.
It was fun to see the 1959 Barbie look in any event.

But are there going to be velociraptors, like when my little niece (who is now in her 30s) used to play with her Barbies? We had some interesting play times together.

I really want there to be dinosaurs in it, now.

There should be. Last time I played with a Barbie was while working for a manufacturing company. I was briefly
watching the son of one of the employees. He had a lot of dinosaurs in his toys and a Barbie.
