This could have been perfect !
The ending I think ruined it , their wa eso many ways it could have ended if you think about it , spoilers—————
One ending could have been that the husband did end up cheating a lot more then Megan ended up finding out and eventually killed her husband or let her husband died and been with Dennis quad. Or the way it ended now but made Megan goods character actually
Not useless and they both tag team killing him brutally together .
