I am not a fan of this narrator. He does other stuff for Science, which I can't recall, but I have felt the same way about him in all the pieces. There is something annoying about his presentation of the content. He kind of reminds me of Casey Kasem. He talks "up" with his intonation but is very flat. If you pay close enough of attention he's almost monotone despite the slight inflection in his voice. I wouldn't watch this again, even as background noise as a result.
As for the content, I wasn't really impressed. It felt like an advertisement for the groups interviewed. I couldn't help but feel I was being marketed to for the projects featured in the program. I may have missed it but there wasn't much "science" in this program as more of a "this is what we want to do - but fail miserably". The speculation from the program directors is veiled with the same misinformation they feed to project investors, pipe dreams and mostly decades away at the soonest for viability of a technology (at least from the private sector). The projects all look are very amateur. As a pragmatist, I don't see any of these projects as the "Game changer" for their respective area of focus. It is still the power players like NASA, CERN and Governments. The groups with the top tier talent and the resources to back it up. It will be the spin off technologies from the big players that might change the private sector domain.
The narrator sucks and should have his narrator license taken away (I know there isn't a narrator license). The presenters are too busy marketing their project rather then going into the science of the project. The projects are very amateur and are no where near ready to back up the claims the presenters make.
This program isn't about science. It's about the projects featured and their marketing teams marketing their project. If you pay close attention to the tech, it's no where near ready for prime time. This is the same marketing tactics they use on there poorly informed financial backers. Once you see that, you can't look at this program the same again. Watch it for that reason alone - to see blatant peacocking, marketing speak, and flat out lies in terms of timetables and readiness.
