-having an episode about a spirit (there aren't enough in the series)
-another example that not all Fire Nation people are evil
-Fire Nation soldiers attacking their own citizens
-a very pointless episode that just wasted time
-we already knew that Katara is obsessed with helping people
-there was no B plot to break it uprating:
This was a complete waste of an episode. They could have used this time to do so many more interesting things...
