Great timing with the thread, I rewatched the show pretty recently (They released it on Bluray so it was a good excuse to watch again) and it still holds up really well. I've watched Korra around the time season 4 was coming out and I thought it was good but it's nowhere close to Last Airbender to me. It had its moments but there's also stuff that brought it down imo. I plan on rewatching it someday as well but I'm in no hurry to do so right now.
I remember watching Korra. I saw the entire series from beginning to end. It was originally meant to last only one season, which is why season 1 felt rushed. But it was so popular and did so well that they decided to keep it going... And I'll just say that it shows in the first half of season 2.
Korra Season 2 pre-Beginnings was, in my view, the lowest point of the entire series. The incredible animation was its saving grace at the time because the writing, especially for the characters (Korra and Mako in particular) was just awful. I was almost ready to give up on the show at that point until the one hour special "Beginnings".
Korra Season 2 from Beginnings onward was some of the best programming I saw from the series since Book 3 of the original. I would put "Beginnings" up against "Siege of the North", "Secret of the Fire Nation", "Day of Black Sun", or any one hour special from the original and I think it was just as good, if not slightly better.
But yeah, I pretty much agree with you about Korra. It had its flaws and is not on the same level as the original, but it's still a damn good show overall.
