This ride has the potential to be one of the best in the world or a pile of crap. From what we can see so far the theming is stunning and lots of details have been added however that is all we can see.
There is absolutely no point in judging what's inside the building because quite simply we do not know everything. If the attraction is heavy in actors I'm sure they will have learnt from previous mistakes and also have a budget according to it being a large investment. I think we need to remember this is not a smal investment of a filler attraction but a hopefully icon to the park.
With the amount of money being thrown at it, they will not have chosen to have the attraction to be heavily actor based unless they knew they could cater for it.
