Picked up a copy of the Blu-ray at a used bookstore. It's been about a year since I read the book, but I think they did a decent job making it into a film. I thought Sal Paradise may have been the weakest, but he may have been like Jack in real life. Despite some who felt Dean/Neal was too laid back (I hear he comes across as more frenetic in the "original scroll" edition of the book before his speech was tamed down by commas and punctuation in the regular edition), I enjoyed the character.
“So in America when the sun goes down and I sit on the old broken-down river pier watching the long, long skies over New Jersey and sense all that raw land that rolls in one unbelievable huge bulge over to the West Coast, and all that road going, and all the people dreaming in the immensity of it, and in Iowa I know by now the children must be crying in the land where they let the children cry, and tonight the stars'll be out, and don't you know that God is Pooh Bear? the evening star must be drooping and shedding her sparkler dims on the prairie, which is just before the coming of complete night that blesses the earth, darkens all the rivers, cups the peaks and folds the final shore in, and nobody, nobody knows what's going to happen to anybody besides the forlorn rags of growing old, I think of Dean Moriarty, I even think of Old Dean Moriarty the father we never found, I think of Dean Moriarty.”
