I didn't so much mind all the love talk. It's pretty much in line with everything Kishi has laid down tot his point, moreso than a lot of random things he's introduced *cough*childofdestiny*cough*.
Go back to the start of the manga - what do we have? Naruto, a loner and impossibly terrible at ninjutsu and Sasuke, a loner and impossibly excellent at ninjutsu. Naruto begins to make friends/bonds and makes leaps and bounds in skill, winning everyone over. Sasuke improves but sees his progress slow and attempts to severe bonds completely to gain strength. Naruto finds roles, becomes a leader, occasionally more calm and focused in battle. Sasuke kills his master his brother and goes to war with everyone else to attain power and becomes increasingly maniacal.
It's more or less the whole Bonds theme except now we know that the Uchiha are nearly hardwired to follow this root once upon it. If Kishi had focused on bonds and comradery rather than friendship and love, it'd probably not feel a tad wishy-washy. It also sets up what I've predicted that as long as Sasuke has his eyes, he will be irredeemable. Sasuke to survive Naruto has to go blind. (or give his eyes to Naruto to resurrect the Ninja Sage).
All that said, good lord Hashirama. That was awful. I don't care if he was always meant to be this way and just didn't get a chance to be way back when, that is nothing like I envisioned him nor was it at all believable that the most powerful Konoha/Senju ninja acted like an over emotional moron. Every panel has had him with perhaps a slight smile or within the intensity of battle. I expected a far more Zen attitude. Numinous is right that it is shoehorning Naruto into the Hashirama role by making the personalities similar (as if that even matters) but it also means Naruto never needs to grow up... which as a kid, if he wants to be a bit crazy and irrational, fine. He's a kid. But I expected he was going to shed that more and more as he got serious about his role in the ninja world and facing Sasuke.
Ah well. Probably an impossible hope in the end anyway.
Good to see Orochimaru mastered the death god without ever really explaining why or how he came across that knowledge after being dead for a long while and focusing on just training and capturing Sasuke for the rest. I mean, you'd think if he'd figured it out, he'd go get his jutsu back, take a new body THEN try and absorb Sasuke... ugh.
A simple souvenir of someone's kill
And like the sea
I'm constantly changing from calm to ill
Madness fills my heart and soul as if the great divide could swallow me whole
oh, how I'm breaking down
