When it's done right, I love a thriller that waits until the last possible second to reveal what's going on. This one does just that, holding out until probably the 90% mark. I was intrigued the entire time, and my only complaint is that the twists weren't quite as big as I was hoping they would be. There were a couple of reveals that fell a little flat and had me rolling my eyes, and a couple of the "gotcha" moments didn't have any prior connections, but overall this is a great, intriguing thriller that keeps its hooks in you until the end. 

Also, fuck Grady. He sucks.
