Finally have some free time to write about this, really enjoyable episode overall.
For the most part the anime original additions were welcome, and everything was presented in a very unique and distinctive way, everyone already mentioned Akiko Sugizono's nice character acting moments so I'm not going to dwell on that too much .
However, I do have two small gripes with it, firstly is that the pervert Momonoske joke is getting a bit old(they did try to do it a bit differently but the fact that they've shown it twice really didn't help it)
and another thing is that it took way too much time for Kin'emon to come out of the Ruins, when in the manga it only took 4 panels with law and luffy talking over most of it.
Zoro fighting a sword-wielding (in its teeth, no less) tiger was just ridiculous.
I would probably agree if it weren't for how well the tiger was firstly presented in that shadowy silhouette, his design itself was also pretty cool so I ended up appreciating that moment.
