The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.
