Wow, definitely didn't expect to see specials that are shown as if they were a single episode of a larger series of the 2 shows worked on in the original Shirobako. If I could rate the 2 episodes individually, the first based on Exodus is a 4/10. Didn't much care for it. It was novel in its existence, but not good. The 2nd though, based on Third Aerial Girls Squad is actually really good! I could genuinely see myself enjoying that as a full anime and give that one an 8/10. In fact, I wish it was a full anime!
