Phillip N @RT54564241 05/20/2023 It's a mixed bag. I like William Shatner and I like the types of subject matter covered in the show. What I expect, however, is objectivity, and unfortunately this show lacks that, as is the case with most of the programs about this sort of material. The program deliberately words things in a way to make it sound more compelling than it actually is. For example let's say there's an episode about people using the power of their mind to fly like Superman. That's clearly ridiculous but if five people on Earth (out of eight-billon) believed it was possible, the show would say something like "Can humans really soar through the skies with only the power of the mind? There are those that say the answer is 'yes.'" It's hard to take it seriously or to respect it. See more Read all reviews
