Life is simply not worth living for down and out school teacher Itoshiki Nozomu. He has no hope of progress, no prospect of promotion, no chance at happiness… he is in despair! Even his name spells 'zetsubou' – 'despair', when compressed. But when the time comes to end it all, Itoshiki's attempted suicide on the first day of the new school year is foiled by relentlessly positive Fuura Kafuka. This saves Itoshiki long enough to meet his new class, and the quirky range of students under his care. Will Itoshiki Nozomu depress his students with his anguish? Or will Fuura show Zetsubou-sensei the joys of life and hope?
They may differ in content quite a bit, but with both being made by Shaft they have a similar feel to them. The animation is fairly unique in both, as well as the direction being fairly unorthodox.
Comedy is also fairly prevalent throughout both series, mainly in the form of fast paced, or witty dialogue that is very well written.
After Shinbo came to Shaft, their animating style became almost religious, and since both anime come from studio Shaft, they share the same overal feel. Both are funky and bizzare to boot. But biggest similarity would definitely be the comedy.
If you enjoyed one for any of the mentioned, then you could also check out the other one.
Meet the bizarre and twisted psychiatric doctor Ichirou Irabu. Occasionally taking the form of a lime green bear, a young man or even a small child, this freaky physician and his seductively sadistic nurse Mayumi deal with all manner of patients. Though in order to satiate his rampant injection fetish, everyone receives the same treatment: a large vaccination, whether they need it or not! From a trapeze artist suffering from insomnia, to an office worker tormented by a permanent erection, to a romance novelist with OCD and stress-induced vomiting, no one is safe from Dr. Ichirou's unique and psychedelic medical practice.
Both these series live and die on the strength of their dialogue. They both use weird abtract imagry to supliment their story telling. And they both have a strange atmosphere that makes then feel a bit surreal at times.
Since long ago, the wolf goddess Holo has honored a contract to bless the rural village of Pasloe with fertile harvests; and in return she has been celebrated and worshipped by the villagers. But as mankind advances, the people have begun to take command of nature for themselves and have made their own god to worship. Holo finds that she is paid little more than lip service, if not outright mocked; and considering the contract annulled, she takes human form and enlists the aid of a passing merchant, Kraft Lawrence, to return to her home in the snowy forests to the north. As they journey together, Kraft finds that he has plenty to learn from this capricious god, and she from him as well.
These are quite different in setting and general tone, but they pair well together when you consider the protagonists. A fairly normal man/teenager boy paired with a supernatural female. The bulk of both shows are made up of dialogue where these pairings match wits. The content of the dialogues are much different, but it's the same style of using a lot of metaphors, along with witty, flirty banter. There's also a certain amount of sexual tension and a good deal of chemistry between each pairing.
A man is miserable. Despite all his dreams of a “Rose-Colored Campus Life” filled with raven-haired maidens who dote on him, his social life is going nowhere. He has no girlfriend, his only good friend keeps getting him into trouble, and the circle he joined brings him no joy. So he tries again, and again, reliving his first two years of college life ad nauseum, making different decisions each time, having no recollection that he’s already done this all before. Will the man ever be satisfied with how his life turns out?
Both of these are unconventional stoires with fast paced, clever dialogue. They both involove the protagonist working through their own issues, while building relationships with others around them. They both have a supernatural element, and use the clever dialogue, along with wierd imagry to develop the characters.
Nekomon has a bit more action, and a ton more fanservice, but Tatami is more clever and much funnier. But both with satisfy your craving for creative banter between memorable characters.
