Amir Syarif Siregar’s review published on Letterboxd:
'Walk the Line' feels a little underdeveloped as it gives more biographical highlights instead of insight. Covering 20 years of Johnny Cash's life, James Mangold concentrates on the key things in Cash's life - his music, the drugs, and his untameable love for the very special June Carter - but not much room for Cash's creative accomplishments. Joaquin Phoenix and Reese Witherspoon are fantastic individually and together. Their fully-believable and credible performances holding the film together. T-Bone Burnett expertly handles not only the score but also production of all the film's music.
