This episode was very well done. My only minor gripe lies with the fact that simply knocking Giovanni off the pedestal to get him to stop being "evil" was a bit anti-climatic. I was also disappointed to see Meloetta leave.
I do believe that the pedestal is the only spot where one can control the Kami Trio. Seems like it was a fatal weakness.
