Hint: it isn't naruto, dragon ball, or anything else popular

The show I'm talking about is Boku No Pico. It's a hentai, which automatically makes it bad enough. But that's not the worst part. What makes it atrocious is the fact that it is child porn. That's the plot of the show. An underaged boy who looks like a girl is being followed by some older dude. The guy makes the kid wear girl clothes and eventually has a sexual relationship. I don't see how anyone could enjoy this. They even tried to make a live action version of this anime.

I mean, I get people hate AoT, One piece, Death note, SAO, and a lot of other popular shows, but I don't think any of those shows are even close to the worst. Searching through the deep Web shows that there are a lot of forgotten animes that deserve to stay forgotten for how bad they are.

Another pathetic anime would be Green Green. I mean, dear God, it makes Pokemon look like a high quality anime.

Its not the worst anime ever made for me cause I never watched it... So... Yea...

SAO still takes that cake with me

Oh not that horrible hentai...

Yea, its fucking cancerous.

I kinda like the first half. Stopped watching after that though.

I've never watched it. Let me try it out

Cleary OP hasn't seen Super milk-chan.

I prefered the second. Though Sinon made it bearable. 

Magical Warfare.
Was expecting a lesser version of Fate/Zero.
Turns out everything about it was unbearable for me - the plot, characters, animation, etc.

Honorable mention: Infinite Stratos (Both first and second season); I still find it unbelievable that it sold better than most anime that was ever release... The industry is total BS at times.

hmm... havent seen it and never will, the worst thing ive seen is called Venus versus Virus, i literally fell asleep...

I mean, picking hentai for worst anime it's like picking early access for worst games.
SAO wins for me too. It's oh so boring.

Guilty Crown or Sword Art Online wins for me.
