I just discovered this thread (sorry, didn't have to time to read all the posts) and since I love reading books in my spare time (don't feel complete without something to read), I'll share my thoughts.
I'm not embarrassed to admit that I've always favored cheesy, steamy romance novels. During the last few years I especially got into a lot of paranormal romance...vampire novels, to be exact. LOL. No Twilight for me, though; at the insistence of a friend who's crazy over the Twilight books and movies I tried the first book but it kept putting me to sleep. I was barely able to finish it. :~ Anyway, over the last year & a half or so my taste has shifted a bit due to the fact that I discovered how fun it is to hunt for used books at Goodwill, so my choices have depended on whatever selections they have available there. I've been lucky because so far all my choices have turned out to be interesting books, mostly crime mysteries (a genre which I had previously had no interest in).
Classics that everyone seems to love and praise are usually just boring to me :( , with "Wuthering Heights" being about the only exception (love that novel). Also, people of all ages seem to love the Harry Potter books, but I don't have any interest in the books or films that center around a boy wizard and his friends. That's just me. *shrugs*
As for the whole 50 Shades craze, that's another that I just don't get. I read the first book and thought there was nothing new or exciting to it. I didn't even think it was all that steamy; it was more talk than action and at times it seemed like the author just had a certain number of pages to fill, so it was a lot of back and forth e-mails between the lead characters and the posting of the relationship rules (forget what it was actually called) over and over. I didn't even bother with books 2 and 3.
Just my opinion. Not trying to insult anyone's taste. ;)
