This episode is not too fun, and there is virtually no action. Probably one of the most boring in the series.
All that happens is the kids explain some things about Gantetsu, and reveal more of his character. Also, this episode fills in all the blanks about Gantetsu.
Other than that, nothing happens. Naruto makes a not so facinating escape from a jutsu, and he's still fighting with the captain. Sheesh, these fillers are getting worse and worse. They finally decided to stop fillers cause they knew that they won't satisfy the audience much more. Good thing, too, because people know when the next part comes out.
