Action sequences can be rather hard to do in books, and yet there are plenty of good ones.

As a reader I tend to like the "less is more" approach most of the time. A few paragraphs of intense stuff rather than page after page of detail, unless it's something really unique.

If any of the novels you read have action sequences, what do you find draws you in about them, and what sorts of things can turn you off from them and knock you out of the flow?
