duet be a wonderful program . it be cute without be sappy or saccharine . who could forget their first date with a married couple in the middle of an argument . the cause of their argument be about family life . in the middle of it all and the date try to compose themselves while the other couple be ready for combat at each other . they try to compose some normal conversation . in the end of their first date and the young couple sit in the first seat while the old couple reunite the passion . it be all about passion and discover one another . it be well than mad about you then and be now . duet be fox first show about relationship . i love the casting of alison laplaca and chris lemmon ( jack lemmon son ) a the argue couple . jodi thelen have a great role a mary page keller sister in the series . mary page keller and her co star matthew or mitchell lawrence ( theyre identical twin and actor ) . lawrence play a struggle writer while keller play a caterer . they meet at a wedding of course in the first episode . they have a great opening segment . it a shame that show do not have the quality it once have like it do then .
