Umbran said:"Official" does not mean "necessary to understnad what is going on". One is supposed to be able to get everything off what's presented on your TV screen. The comics are gravy. Maybe interesting gravy, but still gravy.
I'm a big fan of these graphic novels on NBC.com. I love'em! But I am 100% sure that they are NOT necessary to enjoy and understand the show.
However, they do expand upon and explain a lot about what's going on, and they ARE an official part of the storyline. Think of them as the deleted scenes that will be re-edited back into the show on the Director's Cut DVD (not that it will happen, as they are comics of course and not video . . . although they probably will be on the eventual DVD). Necessary? No. Are you missing out if you don't read them? Yes! (IMHO, of course)
If you aren't interested in reading them, or simply don't care for them . . . that's fine. But too simply dismiss them as "that unimportant extra crap" on the web, well jeesh! I'm not trying to pick on Umbran or anybody else in particular, just surprised in general about some folks reaction to things (this happens to me a lot).
