Poor quiet anime with fabulous, fabulous storytelling and characterisation. They get no love, and this is apparent for Maria-sama ga Miteru.
It tells the story of girls in a Catholic school. That's all. It's them, their lives, and yet it sucks you in like nothing else could, wraps you up in their stories and makes you itching to learn about them more.
There's a little controversy of sorts about the lesbian content of this anime. Honestly, it seems like all the girls are in love with one another, but that isn't the case. There's only one real lesbian in the entire story. So it's interesting to see girls who actually care for one another and are insanely close other than spend their time plotting and hating on one another like other shoujo anime.
I love this anime. I can't think of anything unfabulous about it other than inconsistent art and a confusing first few episodes. It will take you while to get used to the names they call one another.
