Overall, I agree with you. The saying "opposites attract" doesn't seem to be based on experience. At least, it contradicts my experience. In a partner, I'm not necessarily looking for someone whose interests mirror mine precisely, but I certainly want to enjoy films, cuisines, and recreational activities together.
I've been married for 29 years. If I hated everything that my wife loved, and vice versa, I don't think that our relationship would have survived. Our joint pleasures bind us.
Yes, she enjoys some music that I don't, and I enjoy some films that she doesn't. But the majority of our tastes and interests overlap, which is what makes us a compatible couple.
