The ratings for the last two weeks of the Legend of Korra: Book Two Spirits is in and they aren't good. The show's newest episode (as revealed by Zap 2 It's Tv by the Numbers) mustered only 2.1 million viewers compared to reigning original programing WWE Smackdown which won the night with 2.6 and also won the coveted 18-49 demographic with a 0.9, while Korra nabbed a 0.6.
This is down from last week's two-part season premiere which scored a 2.6 (as revealed by Hypable). So far the series' numbers are WAY down from last season which averaged 3.5 million viewers and only strayed into 2.9 at it's lowest episode.
What is the cause of this?
Two answers: the first being that Nickelodeon waited less than a month to give an exact air date to the season premiere to the show (all we knew two months ago at SDCC it was going to debut in September). We knew next to nothig other than that and promotions? Well, other than the short online mini-episodes and a newly released online video game, that's about all Nick did to promote the show. Kind of lackluster for one of it's crown rating jewels.
This sort of shady practice isn't new to Avatar: The Last Airbender fans, with the way the network treated the final season of that show with a large gap and a large share of the final episodes showing up online first before being actually aired on TV. Add to the fact this isn't even the show's original time slot, it was on Saturday mornings at time when almost anyone could watch it. Friday nights at 7 pm Eastern? Good luck watching it live at that time for any normal person.
The other answer might be the fact that fans already know the series is renewed past this second season. Given, it's currently on a timeslot which has been a deathslot for shows in the past and with the knowledge that the show's fate is secured. Fans probably are just watching this show anytime at their liesure (aka like this reporter who's yet to fully finish the first episode of this second season).
