Korra's story is very different from Aang's, and it has some major problems going on but overall it's a great story and any fan of the original should watch it. The flaws seem to have primarily emerged due to the creators not having a guarantee for successive seasons of the show. Each season is essentially its own self-contained story with little overarching plot from season to season. It's just not quite as compelling to watch as the original and if you go into with an attitude of comparing it to its predecessor, you'll likely be disappointed.
On its own merits, The Legend of Korra offers interesting plot lines, decent-to-great characters, and builds on the fantastic world of the original. Korra undergoes significant growth over the course of the series, having experienced great hardships. The tone of this series is more mature and it addresses serious issues masterfully. As did The Last Airbender, the show broadens your soul to appreciate some of the important personal growth we should all have. However, the fact that the show delves into such topics (while certainly beneficial to an adult), is a bit heavy for a child.
Is it as good as the original? Certainly not. But holding anything to such an impossible standard isn't fair, even if it is a sequel to it. I watched it with an attitude of comparing it to the original a few years ago and was disappointed, the second time through I had different expectations and thoroughly enjoyed it.
