As I said earlier, Fresh Prince is one of my favorite shows of all time and honestly I think this darker, more serious take on the show would be pretty interesting, even going back to the sitcom some of Fresh Prince's best moments were it's more serious and darker segments.
As a fan made trailer this is very well done and I hope the director can get Will's attention and maybe they can do something with it.. This is much better than trying to do a continuation with the (now middle aged Banks children and Will) or attempting to reboot it with a girl...
I do think if the tone goes darker, some elements will have to stripped away, Geoffrey is no where to be seen because obviously a wisecracking butler would not fit in this version and while I can see elements of Hillary and Ashley in this darker, modern version I'm curious about Carlton, in the original Carlton was a nerd, a Black Republican but a funny foil to Will and a beloved character but in a more darker and serious version. Carlton can quickly become more of a villain when the ideas and politics of a young Black republican began to clash with a kid from the streets.
