I would've been fine if they ended it with that shot of Tenzin/Korra, they started the show together, fitting that they end it together.
That's what bugs me about that ending, is that it wasn't necessary per se. It would've been very symbolic if it ended with Tenzin and Korra, or to twist the ending a little, have Tenzin mention that Korra should relax and take time off, and offhandedly mention the Spirit World. The final shot would be Korra walking into the portal, turning to see Republic City one more time, and as she looks she sees Mako, Asami, Bolin and Tenzin waving at her and saying goodbye.
That would've been beautiful, touching, poetic, and definitive.
I've already made my comments on this issue, and I'm going to be doing a podcast for the website I work for so I hope to make more sense there (sorry for my monologues). But to wrap up my feelings, it boils down to this.
The last two episodes were great. Truly some of the best of the season. But if this thread has proved anything, the last two minutes have negated pretty much all of it. And that is what saddens me. Cause the fanbase is split (that includes this thread). There are those who say they are, and those who say they aren't, and instead of fully dissecting the finale (yes, I know some of us have, but let's be fair, it's mostly been chatter about this) and determining the true Legend of Korra...we're talking about Korrasami.
Further proof, my tag team partner for my Korra podcasts, we hadn't chatted in a while, and I said in a text chat, "have you seen Korra?" And his reply was...
"I did! #KORRASAMI!"
That what makes me sad. Not mad, not furious, not hating the final episodes or how it ended. It just makes me sad. Cause instead of being appreciative of the finale as a while, many of us will focus on those last two minutes for a long time.
