A Good Story
I have always enjoyed Zach Braff on "Scrubs," but he showed off his writing skills in this movie. It started off somewhat slow, but started to pick up once Natalie Portman's character came on the scene, and really got going when we started to learn the backstory about Zach Braff's character and his family--and then again when he finally started to deal with his issues.
Give this movie a chance. And if you find it slow at first, stick with it--it is worth the effort.
