Should I finish it?

[paigenumber]

It's been a while since I have posted anything. Part of the reason is that I have been finding it difficult to finish some "gothic" books I was reading.  I am one of those people who don't like to leave a book unfinished, even if it may take me a while to finish it.  But as I get older and my vision diminishes, I wonder if it would be worth it. Life is short. Do I need to waste it reading rubbish? One part of me says "yes" because I want to share my experience with others, even if it is a bad one.  It may help them avoid it.  The other part says "no", it is just not worth it.  

Since I have not finished the book, how do I know it is rubbish? The first clue is poor writing - the story unfolds like a summary rather than a plot, no suspense, the ending is essentially laid out in the first chapter (at least it appears to be so).  The curious side of me says "read it and find out if you're right".  The annoyed side of me says, "don't bother".
