I really like the 1920s Shanghai style of the city and its culture. It's a nice direction to take the world of Avatar.

The Pro/Modern bending styles seem much weaker than the ones we're used to, but you can certainly see they're more energy efficient. The two brothers use the least movement possible, and time their strikes, so they don't get exhausted doing something grand and spectacular.

I do wonder if they are capable of doing things like Korra does, or if weaker benders now have some additional options with precision strikes. Why use a claymore when a dagger works just as well?
