The beauty of this movie is that it is real.
I believe I saw myself in many different scenes because that's how life works and how people cope with it.
Rachel's choice to live in LA has brought her closest ones to adapt to her choice, and when she comes back, she has to face a new reality that she probably avoided while living her life far from her hometown.
All the characters around her are awesome: the aunt (drop the "aunt", please) welcomes her like the sweetest and loveliest aunt would do. But then she has to face the other side of the medal, as the uncle is very angry, and her brother Evan... well, he's even angrier.
They all adapted to what the new reality became after she left, and she has to work her way through this new situation.
The way she interacts with these characters and the way they interact with her is so spot on that I couldn't help but feel part of what was happening on screen.
I believe this movie explores "sabotage" in our lives: from who always ends up with the wrong guys, to who holds grudges for years, to who goes into a very dark place of his way of coping with life, and it ends the way it actually ends in life. It's so real it kind of hurts when and how it ends.
Personally, I believe there's nothing bad in this movie - I would have loved it if it explored some things a little bit more, but I also believe that if it did it would have been a book.
