This show was definitely a surprise for me. Umaru-chan is a very simple anime: it has mostly no story. We just watch Umaru and her lazybutt adventures. However, it is surprisingly enjoyable: although watching shows can easily be a bore for me, I watched all episodes in something that was almost a rush.
Story (6):
The story is simply a cute girl who excels at school, sports, beauty, literally everything, but is a slacker when home: she spends her entire day playing games, reading manga and drinking cola. Annnnd, for most part, that's all. Yes. Really, that's all.
Art(9):
The art was pretty good, and kind of helped in the comical effect. Alongside with pretty much everything in this show, it was simple as well, but smooth. I liked it a lot.
Sound(7):
Far from outstanding, but good and well used.
Character(6):
Other than Umaru, there was almost zero character development for all characters. They felt like some stereotypes in anime and manga, however, they managed to be almost likeable.
Enjoyment(10):
I laughed a lot with this anime! I really can't deny it's flaws, but I cant as well deny how fun it was for me. It, somehow, made me remember of myself when I was younger: and this sort of time travel was relaxing and very, very enjoyable.
Overall(8):
Like I said, Himouto! Umaru-chan has its flaws and etcetera, but its definitely worth a watch. It is, certainly, a good watch for the bored ones and it will be very relaxing to the stressed ones.
