My wife and I watched the TV series; dedicated watchers. This is one of those that turn out "The book is always better than movie" although its a graphic novel.
One character (not in show) Wireless. She has the power of reading wireless waves; text messages, emails and computer connect online.
The comics are quick to the point. It doesn't drag out with long periods of unneeded information. Side characters are brought in that were not really touched on in show. Overall if you seen show this a MUST READ! planning on watching show read as well, may help you understand what's going on better.
