This show is awesome and was available to watch as soon as the purchase was complete which is convenient. Only thing I can say bad about it on here and is the reason it is only get 4 stars is this: Amazon instant froze on me several times while watching a single episode and it has done the same thing to me in the past on other shows.I suggest buying the season of Castle for sure but maybe you might want to buy it elsewhere so it won't freeze like it is buffering all the time.
