I just recently got up to episode 19 which is pretty much the final episode.
The two things I just loved were the blooming emotions between Bech and Paige (I want to ship them now) and the introduction of Cyrus. His psychotic personality gave so much personality to the series.
Like the Joker to Batman. It's just a shame that this show is going out in a similar fashion to Firefly. It got moved to a terrible time slot and on top of that the art style was meant to appeal to children.
Seriously, Tron doesn't need any children. It has enough fan base from its older audiences.
