Yeaah so true. Like something along the style of trailers/public announcements would've been great

Honestly, it's not too late for them to make it one. They probably haven't finished much more than we see here, and most of this could be reused by just putting detailed character models over the actors. It'd be even less work than with the sonic redo, as they'd have the environments and animation reference already done. They wouldn't have to worry about lighting the real footage with in game light sources and would have more freedom to tweak scenes now.

It might even be cheaper to do things that way from here on out, as they would already have models of the people in the scene where the actors are supposed to be in the render. This approach makes no sense, which tells me that some producer and/or the director is fixated on putting real people in Minecraft. You could still have them be from our world while not making everyone's jobs harder and alienating the audience.

I really hope some vfx channel whips up a redo of this trailer with 3d characters in a week and the studio actually changes it.
