Doesn't matter how it ends, it'll still be remembered as one of the best Sci-fi TV series of all time. Who knew audiences were intelligent enough for this much mystery, character development, and intertextuality. I'm not sure how it will hold up on re-watching, especially the first two seasons, and I'm not sure I'm willing to commit the time. But watching this every week with friends, gasping at the end of virtually every episode and discussing it non-stop for years... completely worth it.
