The Sasori fight got interesting at the very end, but everything leading up to that was a bit strange from a strategic point of view. The whole point of iron sand is that you can shape it to whatever you want, and manipulate each individual piece to your will. When you have a weapon like that, quantity is far more valuable than quality (i.e. size). He should use it like Kuchiki's flower petal zanpakutou instead of shaping them into two massive blocks.

And as already mentioned, the Team Gai stuff has reached new levels of absurdity. Now they don't even bother making new scenes. Each fight is just 3 second sequences played over and over...
