The 5 Year Engagement - genuinely funny romantic drama about the reality of marriage and the perspective needed. Much like the last movie I watched in this genre (the switch), I couldn't tell if the moral of the story was intentional, accidental or subtle given the culture it was speaking to, but the lesson was a strong one.
Marriage and love isn't about what you can get or the pleasure you can extract, no matter how much society (and the little voice on your one shoulder) screams otherwise (and boy do we like that idea). That falls flat every time, though not always in such spectacular fashion as to be imprisoned in Ann Arbor. True love is found (and obtained) by serving the other person especially when the person and circumstances doesn't inspire it.
"Today's more of a bunny day" is a permanent addition to my favorite lines in film.
