Most people didn't like season 2 especially because of the ending. It's interesting that you see it as a redeeming factor.

:/ Well I certainly fail to see how the backstory about the first avatar, all done in that gorgeous, Miyazaki-esque animation style, along with all that about Rava and Vaatu, followed up by that epic final battle that ended in a huge change regarding the real world's relation to the spirit world was in any way a downgrade from ~10 episodes of really stupid love triangles, Korra's increasingly unlikable personality, Mako's uninteresting cop side-plots which I don't even remember most of (I guess because I was so bored), Lin being uncharacteristically dense, Bolin's typical brand of Sokka Lite humor in that "mover" side-plot that felt like it really dragged and wasn't as entertaining as it should've been, a villain who was way too obvious for Avatar's standards, and an overwhelming lack of spirits in a season which was misleadingly titled "Spirits". 

Honestly the only other decently good part of season 2 was the first couple episodes, which was kind of intriguing with all the spirit stuff that was going on, even if it was hardly focused on for most of the episodes that followed, until the final few episodes finally gave us what the season title, the setup from the first couple episodes and the majority of Nick's advertising promised. 

...Also, the twins. I did really like those waterbender twins. And Varrik, if I'm spelling his name right - or even thinking of the right guy in general. The eccentric guy who hid in that hollowed-out bear that one time - that guy. 

But yeah I feel like most of season 2 was filler and it was kind of hard to get through. The only parts I really enjoyed were the first couple and final couple episodes - the latter of which blew the former out of the water.
