Knowing only limited information about the original Star Trek movies and tv series, I still loved this flick. Similarly I started watching Lost in season 4, and I look forward to every episode. J.J. Abrams has a way of turning every 5 minutes of everything he does into a short sequence of events that you don't want to miss. It doesn't matter when you came in or how much you missed or how little you know. You will still want to keep watching!
