Episode was great in my opinion. Having retrospectives of everything that happened in the past with charachters and their views on it. Plus Varrick's story was the most amazing thing l've ever heard.
It’s not terrible. I do like the Varrick story + Korra/Asami/Tenzin discussion. But, it’s very boring as nothing really big happens. It’s just an episode that was mandated and done in a way to not fire staff members.
I think Bryan's thoughts on Remembraces is a must-read to every Avatar fan. It helps understand the problems during the production of The Legend of Korra
