Task: Question Answering
Input (English): I had trouble putting it down so I could actually get things done . I was thrown of balance a little by the very end though , for reasons which I will put under a cut to avoid spoilers for anyone wanting to read it . The antagonist was of course completely insane . He'd have to be to do what he does to people . 
Question: Why did the writer have trouble putting it down ?
Output (English): They enjoyed it very much .
