Oh, I really enjoyed Dirty Pair Flash, at that time, there were two OAVs. Right now, I am giving Fairy Tail a 2nd viewing. I had binge watched One Piece until all that remained were the new episodes to be released in following weeks. My favorites are exemplified by titles such as these. Sometimes serious, but usually somewhat silly.
In American animation, Brickleberry & the newly released Paradise P.D. are hilarious. Made by the same guys, and using at least one common voice actor, these are silly, but also naughty. They seem to use a similar set-up. Is chemistry the word for it? both have inept leaders, talking critters (1, each) & subordinates who are for the most part, also inept.
Umineko no Naku Koro ni takes place primarily from October 4 to 5, 1986 on Rokkenjima, a small island privately owned by the wealthy Ushiromiya family. The Ushiromiya family gathers for the annual family conference, which concerns the division of assets belonging to Kinzo, the ailing family head. In addition to the twelve family members are five of their servants and Kinzo's physician, comprising a total of eighteen people.
The protagonist Battler Ushiromiya, one of Kinzo's grandchildren, has been absent from the family conference for the past six years due to personal family circumstances. Upon his return, Battler becomes reacquainted with the legend of the "Golden Witch" Beatrice, who is rumored to have given Kinzo ten tons of gold in the past to revive the Ushiromiya family, which had been crippled in the 1923 Great Kantō earthquake. A portrait of her lies in the entrance hall of the Ushiromiya family mansion, and a puzzling epitaph is written below it. It is rumored that whoever solves the epitaph's riddle will receive the gold and become the successor to the Ushiromiya family. After a typhoon traps the family on the island, mysterious murders begin to occur, often in ways that seem impossible for a human to have committed.
An example is that one episode features:
A daughter that confronts then (repeatedly) murders her mother for mistreating and abusing her.
My favorite anime is Hellsing: Ultimate. It's an OVA that covers every volume of the manga, each volume is one episode. The classic anime is pretty much just filler arc (and very bad). Hunter x Hunter is not entirely good--some of the seasons are obnoxious and, therefore, difficult to watch--, but it has the best arc of all time: the chimera ant arc. Shingeki no Kyojin, AKA Attack on Titan, is a modern classic and a must-watch. Twenty years from now, we will remember SnK as we remember Cowboy Bebop and Evangelion today. The new season has 3D Titans though. It's a little ugly, but still worth the watch. FMA: Brotherhood, Parasite, Devilman Crybaby, Interspecies Reviewers, Gantz... They are also some of my favorites--the ones that I remember off the top of my head right know. Asked yesterday, I may would have come up with a different list... One Piece is my second favorite manga (behind Berserk), but the anime has a lot of filler arcs and the sound design is hideous, so I prefer the manga.
For the ones that did not get anime adaptations yet, I have a lot of hope for Chainsaw Man and Spy x Family.
