No, the Fringe-worthy ep would be the one where you get all the blu-rays of the series dirt cheap and then jaunt back from the future to yourself after you saw the first episode for the first time, then gave yourself the entire series right then and there.

That's how I would use time travel.  I would cheat and get myself toys ahead of time.  The ultimate early Christmas gift.  Haven't really figured out how to turn that into an interesting movie.
