Actually, most people are like this with books or movies or other things in their lives; they'll be able to say if they liked a book, or could "relate" to it (whatever that means), but beyond that they won't have much concrete (another synonym for "specific). Which is okay, since they're not trying to be professional writers or critics. But if you are trying to a be professional x (writer, critic, startup), you'd better be willing to look at details, since details are everything.
The older I get, the more I believe details are everything. Well, maybe not quite everything, but certainly 95% of the thing.
One my favorite quotes on design. And as you pointed out, details are key to make something outstanding.
It's easier to bullshit and fluff your paper with generalities than it is with concrete arguments. It also requires less critical thought. Gotta get that word count up. This is a tactic students use on purpose.
Like this example given by pg in http://ycombinator.com/howtoapply.html
"Information is the lifeblood of the modern organization. The ability to channel information quickly and efficiently to those who need it is critical to a company's success. A company that achieves an edge in the efficient use of information will, all other things being equal, have a significant edge over competitors."
