Thermae Romae Novae
I watched the first 2 or 3 episodes of this show a while back and it was okay. There are some genuinely funny moments and the show seems pretty lighthearted overall. The central joke(time traveling bathhouse) did seem to wear thin pretty quickly, but I didn't stick with the show long enough to see if they were gonna do anything more interesting with the conceit.
So I finally got around to watching the first episode of this show on Netflix. I was very confused at first because I thought I had already seen this show. Turns out that the version I saw had much lower quality animation and a more abbreviated story. The Netflix version fills in a lot of backstory and the animation quality is a little bit better. The show is still kinda fun even though they don't really get to any jokes in the first episode. I'll probably continue watching. Don't think I've ever seen another anime, that wasn't porn, where pretty much everyone is naked the whole time. I also like how the Netflix episodes end with the author, in real life, visiting different interesting bathhouses in Japan.
