After seeing some promos with a familiar guest star, I've taken an interest in the show Fringe and have thus far seen the 1st three episodes. One criticism I have read is that it starts to get repetitive. I'm not far in so I can't weigh in on that view myself yet. As I would like to get caught up in a reasonably short amount of time, I am curious what, if any episodes I can safely skip over for now and still have a firm grasp on what's going on in the series.
