The major problem I find is that I just can't be bothered to re-read the previous books. Agreed. I've found this happen a few times. For example, in one series, I read about 6 books and then didn't have time or for some other reason didn't continue. I thought about going back and finishing the series maybe a year and a half later, but didn't feel like rereading the previous 6 books but felt too lost without doing so. This happens to me with TV programs too.
