One Piece 739 has Usopp's operation go badly awry. Will he and Robin be able to salvage it? We also get more information about the toy solider...but this was still only an average sort of a chapter. 

Naruto 666 - much as I like Gai showing up - and it happened in two totally different timeframes here - I'm still too annoyed by the idea of Obito's daft switcheroo to enjoy this part. 

One Piece 738 wasn't a very exciting chapter. Robin's part was simplistic but worked well, but the part around Sugar was just not very interesting. Would have preferred some brief check-ins with the other characters, too. 

Naruto 665 was horrible. Another stupid reversal based on Naruto's platitudes. If this actually contributes to the arc's conclusion I'm going to be extremely unsatisfied. 

One Piece 737 wasn’t exciting like the last chapter, but Luffy’s childhood friend is pretty badass in the arena. I don’t find this silly toy-power girl very interesting, so I look forward to that part being dealt with.

Naruto 663 had the plainly unpleasant image of Sakura sticking her hand into Naruto’s ribcage to manually pump his heart – as though regular CPR wouldn’t do it just fine. Predictably, we’re moving towards fixing the whole issue of the main characters dying, but at least the bad guys get another chance to look good, and Orochimaru is finally contributing.
