This movie will remain a classic for as long as it will stand - I love this film because the humour is never tired out and gives something for (almost) everyone. The positive message is obvious and gives people a good idea of what they can do to achieve. I think Michael J Fox and Christopher Lloyd were perfect for this role and turned it into a legacy. Watch out for some of the content, though, because, although it's done for laughs, Marty has to continually face off his own mother in the 50's and there is one scene of sexual assault. The violence is less imposing, but there is mild peril and menace throughout. Nothing that a child 12 years and up can't handle though.
