Worst anime ever watched?

Well I survived School days, Bobobo, And in my opinion I truly feel "my" worst anime is Aho girl so what is the worst any in your view?

Mine was A Certain Magical Index. Story was great and all, just that the ending was so terrible and left a huge cliffhanger. :'(

I don't tend to rate things if I felt they were below a 7, and I'm not shy about completely dropping an anime if it gets stale, either, so to figure out what the worst anime I ever watched, to it's completion, it's somewhat difficult. I have to say it might just be Samurai Flamenco. Anyone who's watched it will understand what I'm getting at. To be a little more specific though, "Guillotine Gorilla" was the high point of the series, and honestly legendary through anime in general, to me. Everything after that was a sharp downhill fall, however.

The worst anime I ever completed would be Suzuka. It is supposed to be a romantic comedy but both the main guy and girl are completely insufferable. I can deal with bad anime most of the time but that series just grates me all the wrong ways.

I have watched over a thousand anime and I kinda try to avoid dropping a show as much as I could (about 3%). I can say worst anime that I completed is Hensemi and it was torture as hell finishing that show.
