Is compatibility of families on both side important to a happy marriage?

Yes, agree to Nice Mummy's perspective for #14. But I don't think I can ignore the compability of family is a base of a happy marriage. As Nice Mummy's statement, you would find one clue-10 years marriage, it means one people spend so long time to adjust herself to another one. The critical merit is her tolerance. Unfortunately the young person nowadays is less of this merit. For long way to go in both life, compabilty of family as a block was removed. Same background, same life style and like, definitely, will be make marriage more happier,less trouble. I feel this movie is reflecting new Couple status:<New Marriage Age>..
