You would probably like the economist Tyler Cowen's books. There are several but in one (I forget which) he goes so far as to say you should walk out of movies after 10 minutes if you aren't enjoying it and walk into the middle of another. Any other strategy is a waste of precious time.

He writes a ton of book reviews on his blog (marginal-revolution.com), but half the time the review is "I probably won't be finishing this one."
