Why Am I EXCITED about a 2 star review of my book, The Swallow?

The Swallow just got a 2 out of 5 stars by an ARC reader I sent it to back in March 2016. Why am I sharing it and excited? Because even though she only thought it was okay, I felt it was an honest review of my book, and it is exactly what I wanted. I wanted to write a very realistic book even and make it believable.
