I watched the 5th installment of the super popular series, and the premise of a law mandating a National Naked Day in Japan, causing social chaos, is wild and entertaining! The idea of everyday scenes like restaurants, convenience stores, commuter buses, and TV stations being played out naked is innovative and pulled me in instantly. However, it's not a day where assault is allowed, and I felt conflicted watching it, questioning why I kept going despite thinking it shouldn't promote such acts. The concept is amazing, but ending with just facial shots after undressing the actresses leaves me with incomplete satisfaction and loneliness. Normally, it should involve consensual sex with creampies, but the lack thereof makes it feel lacking. The actresses are decently high-level, but the camera work is terrible, and I wish the intimate scenes were handled more cleanly and quietly. There are too many unnecessary male actors that get in the way; for two actresses, about four male actors would suffice, and the rest are just excess. Including male nudity in naked-themed works is a turn-off, as men in clothes are more exciting. I want to shout, 'Stop making repetitive stuff!' and though Part 6 is rumored, my expectations are low but still curious. A highlight is Suzuki Arisu's incredibly dirty feet, which is oddly valuable in a way. Overall, the idea is fun, but there are many issues with direction and balance, and fans strongly desire a more polished work. As a fan, I look forward to the next installment but sincerely hope the improvements are addressed.
