Those following the Falling Skies web comic can now check out the 16th and supposedly final chapter. With the season premiere only a couple weeks away, it makes sense that this is the last chapter that will be released for awhile. I had figured they may start it back up again when the show takes a break, but the TNT website mentions Chapter 16 as the final chapter.
My guess is that if the show takes off they will likely do another comic between seasons. Of course, I don't have any stats on how many views the comic gets so only they know how popular it has been.
