Cradle to the grave biopics (IE Ray, etc.) tend to suffer because they cover too much. There are some good ones of course, but in general. When a movie is focused on one aspect of one's life...it tends to be a better movie because it's more centered on one conflict much like a fictional script. Is GRODT more a young 50 to present day 50 type flick? Or is it more 8 Mile - where you see him come up?
