It must be a good news for those "revolution and grimm fans" that it will be have Revolution Season 2 and Grimm Season 3.

NBC has decided to spare fans a bit of un-due agony by announcing the renewal of five dramas – Revolution, Grimm, Chicago Fire, Parenthood, and Law and Order: SVU – weeks ahead of the announcement of their full fall schedule. Each show will return next season with a full 22 episode run.

Though never really assured of a renewal before, none of these shows seemed to really be “on the bubble” or otherwise in danger of cancellation, especially on NBC, a network in need of consistent performers, and in particular, freshman success stories.

One of those success stories, Revolution, is the top rated new drama among the key demos, and the show’s youthful audience surely helps to maintain good buzz, something that doubtlessly helped keep the serialized series alive after a long mid-season hiatus, a break that arguably helped kill ABC’s serialized drama Flash Forward a few years ago.

Speaking of FlashForward, that show, and countless others like The Event, The River, and V, have all failed to catch and hold audiences’ attention like Revolution has, earning it a place as one of the few so-called “Lost clones” (serialized shows with a central mystery that seem vaguely reminiscent of Lost) to find any kind of sustained success. Though “sustained” may not be adequate just yet.
