Overall, I thought it was really enjoyable, but like most shows there are some slow parts. Each of the seasons has a new antagonist rather than coming to a climax at the end of three seasons like ATLA, which has its advantages and disadvantages. The story is more revolved around relationships and how the characters deal with one another. The show is also a lot more actiony because it comes to a climax every season, so there is always a big finale at the end of each season. It dives deeper into other subforms of bending as well as a lot of the show being based around the spirit world. There are also plenty of characters that are used for comedic relief. I would highly suggest you watch it, but it's kinda rocky to get into. The first season isn't great, but the other three go much more in depth with everything. If you like steampunk and the 1920's, that's kind of where the technology is at this point in the timeline. There are some very advanced tech in it, but it's a show so what do you expect, right? 8/10
