Anyone who's gone through college and lived to tell the tale will confirm that Felicity captures the roller-coaster nature of it all fairly well. (No wonder it engendered such deep loyalty -- and inspired various drinking games -- among its fans.) Friendships founder on the smallest disappointments -- though there are plenty of large transgressions, too -- and relationships (and, naturally, sex) are the source of constant analysis and scrutiny. New ones begin, and those that were once too intense cool off. And then there's the looming question of identity: After four years of learning how to grow up, who do you become?

In its final season, the show took on a decidedly metaphysical bent, with the suggestion of time travel thrown into the mix. (At this point, it also became a bit mawkishly soap-opera-like.) Did everything that happened over the series' run take place in real time, or can the whole mess be undone by going back in time? Confused? Join the club. Still, Felicity "graduated" its lead characters with their charm, if not their innocence, intact.
