I dare say, this is turning out to be the best filler arc i've ever seen in any anime recently. The story behind the rogue shinigami is actually pretty convincing, and the new hollow villains are decent. I'm liking all the character designs. I'm liking too, how the anime is going over the ecology and the natural order of things in Huenco Mundo more than the manga ever did.

I loved that whole 'Nel is an arrancar' skit that the nel bros tried to impress the other hollow with haha, hilarious.
