I mean, wow. They spent way too much time on the history lessons and the Momotaro legend. Then the murder was so sudden, and there was zero discussion of how she was killed, and the confession at the end just seemed trite.
I felt like the episodes were contracted by Okayama Prefecture to promote tourism. There was hardly any of the usual Conan goodness, and a whole bunch of slow, detailed scenes discussing historical locations and showing how beautiful the cities of Kibitsu and Kurashiki were. Sheesh.
So yeah. Eps 377 and 378? Not so much.
On the other hand, I now have another Japan location to add to my to-visit list ;P
