TBH I don't think we should be making excuses for readers. How many times do you allow them to be wrong before you jump ship?? I had a reader blow me away with the first read and five reads later, all sucked. Thank god she wasn't pricey at all, but I'd be the fool to continue to read with her. Once they start to spiral downward and continue to be off, just think about all the good times with the previous reads and move on. So many people continue to make excuses because good readers are hard to find. I truly get that, but to keep wishing and wondering when will they be right again??? Jeez, I really don't know about that one.
