Wow!  What a great flick!  Giamatti is at his best playing this self destructive asshole reflecting back on a life full of bad decisions and good times getting hammered and laid.  Dustin Hoffman plays his ex cop father that is always there for him through thick and thin with whit and charm.  Barney is a low budget film producer looking for love in his early days and finding it on his wedding night but with another woman.  The pursuit leads to a life he had hoped for but his self destructive tendencies get in the way and he screws up the one thing that matters most.  This is a great story of the marathon of life and the reflection upon decisions made during the journey.
