Don't necessarily expect to see the next step in Andrew Largeman's life. While the trailer makes you think "Hey, it's Zach Braff playing another guy who is confused about his life, and not sure where to go from here", The Last Kiss does offer a little more. For one its much more mature, and the characters are all flawed (and not in cute 'Natlalie Portman lies to get people to like her' ways) and they are all real. The performances were far better than i expected, the entire cast shines. The movie succeeds in appealing to everyone. No matter who you are and what state your romantic life is in, you will find someone to relate too.
Jacinda Barrett finally gets to show some acting skills, and comes through beautifully. Casey Affleck is great. Zach Braff makes me understand why he wants something different, despite the fact that Jacinda Barrett seems so lovable. And the biggest surprise is Rachael Bilson. Early on she seems as if she is playing Summer Roberts on the big screen, but as her character unfolds she simmers with sex appeal, and was able to break my heart with just a simple gesture.
The Last Kiss succeeds in letting its actors shine, and if anything you should see it for its great soundtrack.
