I am confused about "have much in common" and "have many in common".
I have searched and I know the phrase "have something in common".
If I want to convey that between Jack and I both like many stuffs and have the same tastes,such as movies,songs,games and so on.
How should I say it correctly,by this way?
Jack and I have much in common so we become good friends Jack and I have many in common so we become good friends
