unlike most movies about cheaters (i've seen) got a different perspective here - the aftermath and how the cheated-on spouses have to literally pick-up-the-pieces, those two idiots left behind. including themselves.
because of who we were "dealing" with - from the get go, was rooting for them to get it on lol, ironically - very childish (cause revenge f*cking is idiotic, u just leave people who cheat on u, trying to get back isn't worth the trouble). but as i kinda read how sh*t was gonna go down (in the description), was rooting for them to get their "revenge".

this could've been very intense and angry, especially given how for both of them, it was out of the blue - they were blind-sided with the fact that their spouses were cheaters, and given the fact that they both (the cheaters) knew each other in college - when this sordid affair started and how long it was going on behind their backs, was anyone's guess.
add to the sh*t pile that they had to now be their caretakers, physically take care of them, put their anger, frustration, betrayal on a back burner - cause what else could they do??. talk about a frustrating situation (me - would leg it. as would worry that i would unplug or try to smother the f*cker in a fit of rage/anger. but that's me).
but both of them turn out to be freaking saints, they manage to put their anger and affront to the side and care for those pieces of crap.

even their relationship - was more kindred-spirits coming together (even though they spoke of sleeping-together as means of getting "back"). not only do they share "being-cheated-on" but that they now had to nurse their comatose spouses. that isn't easy for people in normal loving relationships (that takes a toll) when their loved one r comatose or worst.
so their getting together and then it evolving to something sexual - was not revenger, but two people leaning on each other. it was ironically a love story.

the ending was left open, which i didn't get. read in comments that he left his wife. where/ i must have lost something in translation. same as them both smiling at the springtime snow storm, meaning them coming together. wishful thinking??

usually the ones that r cheated on, especially the docile type tend to forgive and try again. so the pessimist in me doesn't know which way this is gonna go. but enjoyed this - well written and acted.
