The trailers for this made it seem like we'd be watching James Cameron chatting with legendary directors of Sci-Fi films. It looked like we'd get to hear the fascinating topics and ideas brought up by these brilliantly creative minds, and the stories they told about their careers and their famous works. I was excited to be a fly on the wall observing these amazing conversations. We do get that, but it's only about 1/6 of the show.
The rest is other random people talking about their thoughts on Sci-Fi topics. Sure we get some big names like Will Smith and Sigourney Weaver, but most are people I've never heard of. Some are people in the film industry like VFX artists or illustrators, but the majority are just intellectuals or writers or hosts from web sites, publications or radio shows that I guess deal with Sci-Fi. One guy even has the title "Grand Master of Science Fiction", whatever that means. While I don't want to devalue their thoughts, that's not really what I came for. If you're going to be presenting mostly people I've never heard of, at least tell me that in your marketing. Otherwise, I'm going to feel pretty mislead (as I do now).
The show is pretty interesting and worth watching, but it's not nearly as amazing as I was expecting it to be. They had enough good material to make around 2 or 3 good episodes, but they added a bunch of padding to be able to stretch it to 6. I'm guessing it was some TV exec who made that decision.
