Lets see
Akikan!- the male lead is a jerk who collects drinks cans, the girl is a drinks can who needs either to have fresh drink poured into her can or CO2 from "mouth to mouth" to stay alive. There is scraping the barrel, and then there is scraping the crap below the barrel, and then there is this show twenty miles beneath the barrel
Naruto- Irritating characters, voices (in either language) a dumb plot when they keep to it and the most god awful fans ever.
Neon Genesis Evangelion: Death & Rebirth- The first half was a recap of the entire series which only made sense if you watched the series as it choped and changed style and time frame with little regard for pacing or anyone who didn't "get" the series. The second half was simply the begining of the next movie, without any of the interesting bits.
Arjuna - I'm an ecologist, and watching this show made my professional side crawl with the hideous inaccuracies about the natural world. Also the characters were dumber than a goldfish and lot twists more obvious than the sun.
Tenchi Muyo! Ryo-Ohki 3- enjoyed the first series and the spin offs/ re imaginings were fun, but this was another barrel scraper, adding an new girl for no reason who obviously out performs the rest, terrible use of time travel and failing to add anything to the mythos
Gundam Seed Destiny- Gods where to begin. Dumb hot head in charge of the most dangerous weapon the military has... yeah. Oh resurrecting a character who got a plasma blast to the face and had a nice time in open space with out a helmet. Giving away a plot twist away in the opening credits, and moving on to the next set of opening credits before the story catches up. Ditching a season and a half of subtle romance for a saccharine dumb broad with big tits. Making 5 episdose or more of recap and having to rush the ending leaving too much plot dangling.
