The mixing of CGI animation with real images in space documentaries that makes it almost impossible in many cases to tell what is actual and what is just clever imagery. I don't mind the technique in itself, as it often adds clarity and vividness to the actual images, but I wish it would be made clear which is which. These days anything can be made to look real and it bothers me when I can't be sure that what I am seeing is what was actually photographed. What is the point of space probes or nature documentaries at all if it can all be deep faked?
Far worse than this has been going on for over 50 years!
