Arguably UC's animatronic tech has improved since 1999, and looking at Pets' teaser, the animatronics will be fairly easy to pull off. They're all small, simple characters, and Illumination's simple but colorful scenic design is practically an accountant's wet dream. I mean, Minions only cost $76 mil and netted Universal over a billion dollars and I bet Pets will have a similar budget. So it'll end up looking like a low-rent, but cartoonish Kongfrontation.
I also think video screens will be utilized (I mean, apartment windows offer the perfect opportunity), but they won't be the focus.
On a sidenote, I should probably input that I rather dislike Illumination and their output film-wise. And yeah "Pets" is the same thing for me right now. The teaser is insanely pandering and this is coming from a person who has owned (and still owns, and adores) pets. The story of the film is basically "Toy Story" with cats and dogs. (seriously read the plot synopsis:
https://en.wikipedia.org/wiki/The_Secret_Life_of_Pets) As you can see, I'm a total animation snob... however I can't mistake the appeal of their products and they do make for engaging attractions. The humor works when they don't have to focus on telling a theatrical story (because they're
really bad at that), so I'm all up for attractions based on their stuff.
Except "The Lorax". That was an insult to Seuss as much as the live-action Cat in the Hat was. That movie needs to rot in hell.
