I was confused with iZombie because I'd always thought that it was doing pretty well last year, but for season 2 I kept seeing so many comments about the ratings and how it wasn't a good sign that it didn't have a full season order, so I was starting to worry as well. I wonder if it'll be 18 episodes again, or 22 this time? Not that it really matters I suppose, I'm just as happy with 18, but it seems like a bit of an arbitrary number when most shows either have half seasons of 12/13 episodes, or full seasons of 22-24 episodes
