People make no sense

I just don't understand people! We've had ongoing trouble with selecting a book for my book club. We nominate books and then vote online, but we seen to end up with books that people don't like, or worse, don't want to read, surprisingly often.  When we sat down tonight, two of the active members, both in their 20s, said they thought we should pick more contemporary books (3 of the last 4 books were at least 20 years old and the next book poll is first-book-of-a-popular-mystery-series, so of course, most of those books are pretty old too). I wholeheartedly agree (and I've repeatedly suggested book club favorites from recent years to try to address this, but that's another conversation). So we discuss the current book for awhile and then get back to considering future books.  We decide to go with a theme mentioned previously - books made into movies.  We brainstorm some titles, trying to stay within the last decade.  Then one of the young women who said we should pick more current books suggests The Hitchhiker's Guide to the Galaxy (published in 1979 and made into a movie that no one saw) because it's "hysterical."  I said, "I thought we wanted to pick more current books," but she just plowed on, saying how great it was.  This is EXACTLY how we've ended up reading books from 20, 30 and 40 years ago, and it's exactly what SHE AGREED we didn't want to do!! W-T-F???
