Let me start by saying, the title is misleading.
You might think that this is about a married couple (or couples) who have a "free" relationship and it is allowed to sleep with other people, have one night stands and so on.
Far from it and far from original, this is the story of 2 students (a "boy" and a "girl") who had a fling back in the days and meet again after 15 years but they are reluctant to begin a relationship between them. They try to stay friends and keep their relationship platonic while they keep denying the physical attraction they have to one another.
So, it is basically a "When Harry met Sally" rip off which tries to implement a more raw "sexual" and comedic style.
Despite the fact that this is rated "R" there is no nudity or vulgarity which makes it a bad decision to rated like that. If nothing else they lose tickets without a cause.
The 2 leads are somehow likable but I wouldn't say that they have a strong chemistry together. The rest of the cast is mostly unsympathetic especially Adam Scott who plays the man-trophy in this.
It is not funny per se. Near the end the things might even be considered dramatic with a scene that seems pointless and out of the blue, just before the obvious (from the start), forced conclusion.
There are some technical problems too. The direction and especially the editing are amateurish especially at the beginning of the movie.
Overall: I understand that there is some hype about this movie and some people are excited to see it (maybe they misunderstood the premise too). But this is overall a sub-par movie, trying to wear the shoes of a rom-com classic.
