I realized going into this film that it was not going to be a straight bio-pic about Rimbaud's life so that loosened my expectations for the movie a bit, which is good considering had I expected a life story I would've been sorely disappointed. This film is more about Rimbaud's rocky relationship with fellow poet, Verlaine, whom he falls in love with and subsequently about Verlaine being stuck between a rock and a hard place with Rimbaud on one side and his beautiful but ultimately empty headed wife, Mathilde on the other.
The set/costume design was done well enough; not enough to win awards but enough to make the time and place believable. What stands out the most, though, is the acting and of course the wonderful violin heavy score. DiCaprio gives an inspired performance as the young, opinionated, Rimbaud as does Thewlis in his role as the older poet, Verlaine who takes him under his wing. You won't get a complete round view of either man or his life here, but what you will get is a story about love, madness, writing and the search for meaning.
If you like what you see of Rimbaud from this movie, I would whole heartedly recommend his work to you and any and all written biographies as they will shed even more light on a truly great poet's life.
