i admit that i be a bit puzzle by the perspective of this movie . all the way through and it seem to be build to the logical conclusion that the four main character be go to end up swing together and culminate in alice expect suggestion to the other three that they have an orgy . all the way through it seem to be a celebration of the sexually free wheel 60 and with bob and carol essentially enjoy an open marriage not only have affair but tell each other about them and sometimes even meet each other lover and basically try to convince ted and alice to join them in this lifestyle of freedom . then and in the end and it do not happen . that do not upset me i be please by the end of the movie and but still surprise . the lasting message that i get from the movie be that and ultimately and sex without love be an empty thing and but love without sex be a wonderful thing . thus and the conclude scene of the four decide that their friendship make it impossible to begin a sexual relationship and the eye contact they make with stranger while on their way to the tony bennett concert and while all the way the closing song ( what the world need now be love ) play in the background . i love the end and think it perfectly appropriate . i also love the beginning of the movie with the encounter session which be absolutely hilarious . robert culp and natalie wood and elliott gould and diane cannon a the respective title character be fantastic all the way through and and their performance make an interesting story even well . the only thing i never really figure out be the decision to open the movie with the hallelujah chorus . what be the relevance . i wasn not sure . small point and though and in an overall great movie .
