This is a definition of light, breezy movie. You expose two recently broken up characters with different values interact with each other with lots of misunderstanding and slowly recover from their pasts in a 2 hr movie.

Both main characters had sufficient depth and character growth, even when we get frustrated at the perinniel drinking or bad mouthing, we slowly warm up to them and what caused them to act this way. And we see some definitive growth by the end.

Except for excessive alcohol induced interactions, I would definitely watch this movie again
