The first character-centric episode of the season is always a big occasion. It is the first opportunity for the new writing staff to depart from the formulaic opening and begin character development. This episode, did not seize that opportunity. In my opinion, where the Mighty Morphin' episodes of the same type provided insight into the character (the first example that comes to mind is Zack with his hip-hop fighting style, which in hindsight was incredibly racist), this one was merely used to teach a simple lesson to children. I do commend it however for not taking the Disney Channel Approach and saying "today's lesson will be..." and at the end saying "today's lesson was..." However, if you did make a drinking game out of the episode and took a shot everytime Noah said "I believe in myself" in some form, you would die of alcohol poisoning. I think that too much of the episode is devoted to the fighting, something that was apparent from last week's episode, but I wanted to give it a chance.
Spoiler: Noah got new zords and the Sea Gosei Great Megazord was unveiled.
