Love this movie, but it sends a horrible message
The movie is just extremely sexist. The fact that Lance cheated with all those women over the course of his relationship, straight up embarrassing and humiliating Mia for years, yet we as viewers are supposed to view his multiple offenses in the same light as her one error? Made my stomach churn that the writers just let that stand. I mean they didn't even have any of the female characters call his hypocritical behind out. I actually came away from it not even considering what Mia did as a bad thing at all, because when her 'partner' was out there cheating on her and openly behaving like a single man, were they even in a relationship for Mia's sex with Harper to even be considered cheating?
His hypocrisy actually wouldn't have even been that bad if they made it just a character flaw for him, instead of an overall plot point that they justified. What made it bothersome is that the filmmakers never confronted that part of problem head on. No one ever checked Lance and said suck it up because for all the crap you put your "ideal woman" through, you should be happy she even graced you with her hand in marriage and that she's even still dealing with you. There was no learning moment for him or the audience.
I still think its a great film and rated it highly, but it would have been perfect had they not just let that sick line of thinking stand. That Mia cheating with one guy was the same as his dozens maybe hundreds of affairs. Granted, it was his best friend that she cheated with, but I have no doubt he slept with a few of her friends/associates/maybe even family members while he was out hoeing so that doesn't stand.
Boom.
