1. Back To The Future
Marty Mcfly goes back in time accidentally and manages to change his family's future completely, making George McFly a much better man and ensuring their marriage contains a lot more love and affection. He dates his mum and forms a close relationship with his dad. Yet neither remember his alter ego "Calvin Klein" whatsoever, despite him having profound affect on their lives, even when their son looks exactly like him. Not to mention that in the new 1985, Biff works for George and his wife, and the two exchange some light-hearted banter, despite the fact that he tried to rape her thirty years ago. Forgive and forget, I guess. So, anything we might have missed? Drop us a comment why don't ya...
