the film lacks 'soul'
In this film, the actors over act in parts and I never sense any "truth" from the actors who played the real people.
The book, On the Road, is haunting. I read it and became obsessed and possessed. This film never even comes close to getting inside me. It seems miscast and the actors seem to have no sense of the material. It's superficial and the actors are so wrong. They just do not get it right.
We never get any sense of "the man," Sal Paradise. The film never delves, it is superficial and it's just sad.
In On the Road, Dean was on a spiritual journey, and in this film we never get any sense of his inner life. He is just one dimensional.
The film lacks heart and it lacks soul. There is no real feeling. I felt nothing.
