I don't think so, life really is too short to persevere with something that isn't to your taste. One of our members declined to read much of the our last book once she'd read a couple of chapters, she was quite honest, said she didn't like the content. Books are incredibly subjective so it's understandable what floats someone else's boat may not be your cup of tea.
Since joining my book club, we've been going about a year, there has only been one book that I thought was excellent apart from my own choice 
and that book "The Women" had been lying on my shelves anyway, I hadn't got round to it. I like the social aspect, but some of the choices, have been okish, a couple a bit boring, but I've got through them.
