My own opinion is that part of the fun of book clubs is the difference in opinion. If everyone thought the same way, then how are you going to open my eyes up to a new perspective? And I also think that life is too short to be miserable. If you continue to not like the book selections or feel like it's more of a job than a discussion, then maybe it's not the right place or maybe just not the right time.
