The whole concept behind this episode could have been good. It could've been really neat, actually. But somehow, through the power of bad animation, the concept of Luffy, Bartolomeo, and easily one of the better filler characters in One Piece rolling around a wacky broken mineshaft environment while being chased around by a guy who can turn into a cart is just… boring. Here's where Toei really had a chance to shine, and have the sort of fun, lively action scene that just wouldn't be possible in the manga format, but instead it's all just so lazy, with no love or creativity put into the choreography at all. I found the storyline to be much in the same vein as well, more coasting along to fill time rather than actually telling a story, with some of the most flat, lifeless scenes I've watched recently. It genuinely feels like nobody who was involved with this cared about the product they were making in the slightest, and as such, I don't care either. I can't even be mad at it, it's just so... drenched in apathy. The fact that it's all set in a cave that consists entirely of various shades of grey doesn't help much either. Again, not everything is horrible. Desire is a high point and I do like the concept of the cart battle if not the execution, but even the good things they have, in context, seem so very squandered. I'm still baffled that Toei thinks they can get away with this, but not surprised.
