And what this could have been is so, so much more than it was.
good, disappointed in what it actually ended up being, and also, disappointed that it wasn't what it could have been. Now, if you're going into Blind Spot expecting it to be a thrilling, edge-of-your-seat murder mystery, as both the synopsis and trailer made it look like it'd be, then run away from this book like it's a madman coming at you with a butcher knife. Sure, it may just cause a scene, maybe even get you locked up in a nice little padded room, but at least you can say you've escaped the clutches of Blind Spot and its deceit.
Disappointed that I went into Blind Spot thinking it'd be, well... Your enjoyment in this novel boils down to one major thing (but that's not to say there aren't other reasons why you'd be disappointed in Blind Spot), and that one major thing is what you're expecting Blind Spot to be.
