Interesting how two different people read the same book and have very different reactions, but with completely valid opinions. It's almost like--gasp!--people are different and don't need to conform to everyone else's opinions. I like how we got two different reviews for this book, showing two very different opinions.
Personally, I lean towards Grey's review, as I LOVED Starsight, but I don't dismiss Jebus's opinion. His review was entirely valid.
As Wit explains in the Oathbringer epilogue, all art is subjective. Everyone's going to enjoy this book differently, and THAT'S OKAY.
