5/5
This chapter showed us a piece of history that draws parallels in all the stories we currently know in Naruto. It shows the basic relationship between Madara and Hashirama, in the past, future and the present.
The past: The flashback has showed us that Madara and Hashi had some kind of basic friendship going on. How those two enemy clans have met in times of war (at least those two kids) is a little of a mystery to me, which gives that meeting even more meaning! The pebble-throwing "contest" also reflects with the thrown bijuu-shuriken.
Also, the battle clearly shows that some kind of bond was forged between those two individuals. To what degree and to what extent is yet unknown, but I'm happy to find out next chapter!
The present: Well, I think we can conclude that the relationship between Madara and Hashirama is still very tense. The reason of this can be found in the way that the 'big battle' was fought. Madara, being emotionally obsessed with pain and suffering, decided to write Hashirama out completely. I think this had its consequences. Madara wants his brother back with his "Eye of the Moon plan" but also wants to be as powerful as Hashirama, as I feel that since that pebble-throwing contest when they were kids, defined the basic relationship between Hasi and Madara (which is that Madara is under Hashi)
The future: The past always repeats itself in the future. I think we are sure to see a legendary re-match between those two. To what proportions this will be fought at, is yet unknown...
Conclusion: This chapter revealed a lot of hidden information that people just glare over very swiftly, resulting in very superficial reviews as: "Another flashback, boo!" or "We already knew they had an epic battle, next chapter, please!"
Worthy of a 5 on 5!

People who are whining: Please STOP. You're talking about the BASIC legends of the freaking Manga...
You realize you DO NOT have to read it, do you? YOU CAN READ IT FOR FREE. At LEAST a basic feeling of gratitude would of be the order. In my opinion, people who ramble and complain hard core (with no arguments) should be banned from these forums permanently...
(Before you call me a fanboy, know that I'm completely capable on giving a chapter a 1/5 if it truly deserves it.)
