I have asked several people to help me answer this question. Here are some of their comments. In the meanwhile Please consider this question next time you start reading a book you do not like. Should it be Read? Remember that there are a lot of books to be read and life is short.
"If you really don't like it, give it up - there's so many great books to read!" - Nicole
"And I say a resounding no! There are too many good books to read for me to waste time on a one that I can't get into. I usually give it about 50 pages or so. Then I move on." - Susan
"No, you should not finish it. There are too many good books to read and the next one you choose may be great. I used to think I had to finish a book no matter what. However, since I have so many and there are so many coming out all the time, I give myself about 50 pages. After that I am tossing it." - Teresa R.
"I like more of what I read than I don't - and either I'm very good at selecting what I read -- or I am just not as discerning as some. I keep plugging along when a book has captured my attention at some level. I've come across several books that ended up being among my favorites that just got of to slow starts. I won't bother finishing books that have completely failed to suck me in and cannot hold my attention." - Wendy
"If I don't like a book, I won't finish it. Reading is supposed to be fun and what fun is reading a book you don't like? I say move on to a better book." - Devonna
"I am not inclined to keep reading a book that does not catch my interest. However, that being said... if I am participating in a book club read, I will slog through a book I don't like. The reason for this is that often during the course of a book club discussion, I have found myself appreciating a book that initially didn't interest me. Sometimes discussions open up interpretations which I may have missed. That happened to me several times over the course of the year." - Wendy
"There have been times that I have finished a book simply to say that I have read it. I find that if I do not like a book and it takes me a lot longer to read the book than if I really enjoyed it. Nonetheless by finishing the book I can say that I have read it, thus giving me something to talk about, and it also gives me something to think about. I find that when I read a book I always try to figure out the significance of the title and when there is a book that I don't particularly care for I find this job more of a challenge, so, in the end I find that reading a book I don't care for proves to be a benefit." - Jenn
