I didn't like the Morita-san ha Mukuchi ("Morita-san is Taciturn") OVA. The jokes felt overused, and the writers particularly seemed to think that the two boys who kept drooling over Mayu and her friends were a lot funnier than they actually were.
The Morita-san TV series remedied the OVA's problems by keeping each episode short and sweet at three minutes and focusing almost entirely on the girls' perspectives.
Morita-san ha Mukuchi is about a girl named Morita Mayu, who over-thinks what she says before she can say it- resulting in her never really saying anything. Her friends Miki (the extra-chatty one who is a little boy crazy), Hana (the soft-spoken one who has a bad home life), and Chihiro (the other chatty one who acts as a foil for Miki) don't really mind, since they know that that's just how Mayu is.
You also have the nameless glasses girl who crushes on Mayu from afar and Yamamoto, the cool Class President who has a lot of fangirls. In volumes three and four of the manga, we can see that Yamamoto herself likes girls. As I recently mentioned, I want to see more Morita-san animated just for that. Mayu's parents occasionally show up also. Where their interaction just made me feel bad for Mayu in the OVA, in the TV series, their relationship feels more sweet than bitter.
Each episode focuses on a slice-of-life scenario: the girls figuring out how to beat the summer heat at school, a festival, shopping, Mayu rewarding herself for a good score on a test, a sleepover, the girls taking a part-time job selling Christmas cakes, etc. If you like this type of series, you'll probably enjoy Morita-san since its characters are likeable and have good chemistry as friends. Thankfully, the service is basically nil.
For a light, yuri-friendly pick-me-up, Morita-san is a good bet.
