10. The show’s mythology isn’t that hard to follow.

Under lesser writers and producers, Fringe could very easily give viewers unbearable migraines. Entering its fourth season, the show has firmly established a parallel universe where the characters’ duplicates exist with opposite personalities, and most episodes flip-flop back and forth between worlds without announcements. And in the midst of all the universe-hopping, Peter Bishop, one of Fringe’s major players, has, per the mind-blowing Season Three finale, never even existed. Or has he?

That question is the crux of Season Four, but as faithful viewers tune in to see where the hell the show is about to go, they all do so with ease, knowing that the brains behind Fringe are master storytellers. It’s as if the Bad Robot team has learned from their Lost follies (i.e., muddled narratives and meandering subplots) and have been using Fringe to demonstrate their written maturity.

This doesn’t mean that the uninitiated should jump right into Season Four without any background preparation, though—Fringe is still an intricate series that demands to be experienced from its pilot onward. But the millions of sleepers out there can feel confident that their brains will be massaged throughout, but not with any pain.
