Some people like hook beginnings. And there are some great hook beginnings out there - my personal favourite is Iain Banks' The Crow Road, which opens with "It was the day my grandmother exploded."
On the other hand, a hook beginning needs to be followed up pretty solidly to justify it. And there are a lot of great hook lines that have books following them ranging from so-so to mediocre. [ "You are reading this book for the wrong reasons" would be a great opening line if the book following it was actually any good at all, for example. ]
Myself, I like nets more than hooks. I pretty much never put down a book unfinished, and I read fast, and I'd far rather have a first chapter or two give me lots of little things to like than gamble on one big hook and have it fail to work for the people to whom it clearly says "this is not my thing".
