Edo never sleeps, but your brain might during this. Going in blind to the manga I’ll be objective to the OVA only. Exceptionally average, Oedo wa Nemurenai! Offers a historical setting in 1700s yoshiwara. The famous pleasure district. Our main character is quite a young woman and Oiran and is for some reason important you’ll find out. (also pay attention to that cat!!! What happened there) Production quality is at most times quite poor, out of sync voice acting, many still/panning shots, and very low movement. This is all to be expected for something low budget. For anyone who has not read the source material theplot is quite choppy as nothing is clear since context is not given for anything. Unclear relationships, confusing cuts etc...
Sound is nothing to write home about either as the music is a mix between win-dings like synth sounds and orchestra garageband samples. Gratefully the voice acting is fine.
The main issue is there is no explanation as to why anything is happening and who these people even are until after it should have been established by some clue. Regardless for a half an hour it is not unbearable and most likely complimentary to the manga. In all honestly it gave me a few chortles as to how ridiculous it was.
