So, basically, Falling Skies again. I honestly can't see the intrigue, to me it sounds like a completely generic outline. It's what Hollywood has done for the past 30 years straight, which is probably why he was able to sell it.
To be honest I'm not a big fan of J.J. Abrams' work. I had some fun with Alias, and I somewhat like Person of Interest as a mindless, oldschool action thingie. I absolutely disliked Fringe (although I was probably a bit put off also by its low budget), and I fear that Abrams' influence on Lost was felt most where I stopped liking it (its final 1-2 seasons). What I associate with Abrams' series is what people call "typically Hollywood" in a condescending way -- shallow, stereotypical characters, predictable plots and a complete disregard for real-world logic and physics. There's shows where this doesn't bother me (again, Alias or Person of Interest), but most of the time it does.
What this one-sentence plot outline of Revolution tells me is Falling Skies or Terra Nova. The former was at least somewhat suspenseful, so I ended up watching it, but the latter was so hackneyed that I didn't last through the pilot. So I'm twofold and threefold more skeptical of Revolution.
