This second season of Haruhi Suzumiya proved to be much weaker than its first season. Plotwise, the series fills in the gaps of what took place in the first season, such as the filming of Haruhi's movie and Kyon learning of Haruhi's past. Episode 1 was the strongest episode of the series providing Kyon the opportunity to see a younger Haruhi and getting in some predicaments with Yuki and Mikuru along the way making him an integral part of Haruhi's past. But from that point, this new season starts going down hill quick. The biggest contributor of this mess being the infamous "Endless Eight" episodes. The whole time loop storyline stretched on for a whopping eight episodes and outside of alternate camera angles and different clothes wore by the characters in each of the show's scenes, just about every event in the episode was the same. As a matter of fact, you could skip episodes 4 through 8 and you wouldn't really be missing out on anything since no major plot developments really occur within these episodes as the plot progression in each one is the same as episode 3.
The arc with the movie being made was also a bit of a downer thanks to inconsistency with character development from Haruhi. Considering the developments Haruhi's character went through following the Melancholy episodes, I had thought there was some slight maturity of her character following these events as the Remote Island episodes shown she did care for the well-being of the SOS Brigade, while being too prideful to show it on the surface. But her abusive treatment of the group in the movie arc didn't match up to her playful treatment of them in the first season which made me question the direction of Haruhi's character development that the series followed. The saving grace to this arc was that Haruhi's fun with the movie got out-of-hand enough where it was creating some unusual things in reality.
Visuals were of above-average quality with plenty of rich detail and color in the scenery with fluid movement coming from characters and the environments they are in. Music was a bit average in quality not comparing with the upbeat rhythms and musical selections of the first season.
Haruhi Suzumiya's second season was highly anticipated by fans with enough rumors that circulated online regarding what the series would cover from the light novels. Unfortunately, this series only succeeded in filling in gaps that the first season lacked the time to cover and even pushed the viewing tolerance limits of its viewers with the Endless Eight episodes. If you have yet to see the series and liked the first season, then you won't be missing out much from this new season of the series. Just skip it and wait out on when the Disappearance of Haruhi Suzumiya movie comes out next year.
