How much does your mood affect your reading?

I wonder about this a lot, because I go through stages. There's the times where I devour books and luuurve everything I read. Then there's the times where I read slower, where I'm just not that into reading, or into a particular book, and where I notice flaws and things tend to annoy me.

Am I just in a bad reading mood? Is this totally unfair to the books I read when in said mood? I could easily say yes. But at the same time, something usually pulls me out of that mood. Something, as in, a great book.

A really great book would pull me out of a reading funk. I really believe that. If the book is AWESOME, I'll WANT to read it and I'll be EXCITED about it and ta-da! No more bad reading mood. So I think there's something to be wondered about the books that don't get me all revved up, bad mood or not.

But mood definitely plays a part. If I was in one of those la-la-all-books-are-wonderful moods, I end up loving a book which maybe doesn't deserve quite so much praise. And while I'm in the reading dolldrums, good books get picked apart a little more thoroughly than normal.

So my mood affects my reading. What about you? Does mood affect your reading? Or is it only about good books vs. mediocre ones?
