I kinda wish they'd bring filler arcs back, like Ice Hunter and G8 sized, or like Post-Enies Lobby style, as mentioned a few posts above. I rather like having original story arcs in the anime. They're usually charming and/or really bad, but thinking about it, it's kinda nice to reminisce about those horrible episodes that took place right after Alabasta, like that goddamn episode where Sanji taught the red-headed marine kid how to cook. Some of that stuff falls into so-bad-it's-good territory, lol. None of that alternate reality stuff, I hated those.
As for this episode, I thought it was aight. Nothing I'd go to the effort of watching again. I'm getting pretty stoked for the Fishman Island flashback.
