Looks like all of CW's comic book shows are hits and not just that, but they've all been picked up for new seasons. According to Hitflix, CW has picked up iZombie for a second season. It will be joining The Flash and Arrow in the growing list of comic book shows that were renewed for new seasons.
While the numbers for the show aren't as strong as some of the other comic book shows, iZombie pulled in 1.62 million viewers with the most recent episode and received a 0.6 rating among adults 18-49 with live and same day viewings. This is apparently strong enough for CW to give it another season.
