That doesn't have a problem with this? Movies aren't documentaries. They've been using special effects since like forever in film. This is just another special effect. This seems to have been done very well. I don't even get the "uncanny valley" feeling even though I know it's AI, so they've obviously put in a lot of work, which shows a lot of respect to the late Val, and his estate/family. I think what will suck is if/when this tech is normalised, and they get lazy and don't give it as much polish. So even though I'm saying that the trailer on *this movie* looks fine, I reckon we'll be seeing some very crappy/cheap implementations before too long. Critics will just have to sharpen their pencils for when that happens.
