Maybe because I'm a child of the '80s, but for me, a sequel is a story that follows the previous one, and sometimes if you haven't seen the original, then you don't understand the second one. Like 'Back to the Future 2.' If you haven't seen the first one, you're not going to get anything out of 'Back to the Future 2.'
