For that one comment on YouTube saying that this opening felt like a reward for watching the fillers, yes. Yes, it does feel like a reward.This is the last opening for the first series of Naruto that led to Shippuden. What I mean by that is... literally, the very last episode is when Naruto leaves to train with Jiraiya.
The part where they show the boys in their suits and different hairstyles is better than the parts with Naruto and Lee sparring in a taijutsu match in my opinion.
Just look at Neji!
...If only Sasuke was there. Just saying, it would've been more entertaining to see Sasuke in these fillers with the rest of the characters.
Remember when Temari was considered a bad guy? Yeah, I remember. Looking at her now... not really. She just gives off her big sister energy.
This feels like an ending though if you really think about it, but at the same time, the ending after the episode is what really led us to the second series. If you know, you know.
Overall ranking, 8/10.
