At the bottom of the status option for any anime is a strange little setting called "won't watch." Won't watch means different things to different people, but the criteria is usually the same; the anime appears to not even be worth taking 25 minutes to watch the first episode. While there are several anime that I probably will not watch, I only mark an anime as "Won't Watch" for two reasons.
1. Some personal aversion that I will justify bellow that prevents me from even watching a single minute of the anime.
2. After watching partway through the first episode, I dropped the anime and never intend to watch it again.
There are 22 anime on my "Won't Watch" list. I will attempt to briefly justify them all here.
EDIT: After many years of having this blog up, I changed the title from "Series to Avoid" to "Series I Avoid" since it's an entirely subjective list. If these are some of your favorite anime, that's fine. There's just no way I'm watching any of these anime.
Aki Sora: After having read some of the manga, I really don't see the value in watching animated incest and perversion.
Arcade Gamer Fubuki: Combines my two least favorite genres of anime, gaming and cheap ecchi.
Beyblade series: A cheap rip-off of all other gaming anime. It's card games on motorcycles battling with TOPS!
Bobobo-bo Bo-bobo: Too many "b"s The concept is revolting. Bad reviews across the board don't help its case.
Power Puff Girls Z: After watching partway through one episode just to see what it is like, I rapidly searched the Internet for some original Power Puff Girls episodes to bring me back from the bad acid trip that was Z.
Digimon Series: For some reason, I cannot enjoy this show and Pokemon at the same time. Don't ask me why.
Dinasaur King: Saw it while flipping through the channels on Saturday morning cartoons. Two words: LOL WUT?
Duel Masters: I'm surprised there wasn't a lawsuit involved in the making of this anime.
Medabots: Card games on motorcycles. This time, it's with ROBOTS.
Pokemon: Pikachu's Island Adventure: After about five minutes of narrator "translation," I passed out from hitting my head against the wall too many times (not really but you get the idea).
Sergeant Frog: A tad too random for me (and I enjoyed Lucky Star).
Sonic Series: I never was a fan of the blue speedy hedgehog and don't ever want to become one.
Kiss x Sis: Panty shots, incest, perversion. Seen it all before and terribly animated. Fell asleep about 8 minutes into the first episode due to boredom.
Amagami SS: As soon as I read that "the story of the anime will be arranged in an omnibus format, with each heroine getting her own version of the story animated. Each heroine will sing her own version of the ending theme song," I shouted NO FREAKIN WAY, and added this to the list (but because of my curriosity about harem anime, it probably won't stay there for long). Took off because, well, harem anime are sort of my forte, so I'm tempted to give it a try. Not in the near future though.
Pokemon Best Wishes!: I almost shocked myself when I added this to my won't watch list. Pokemon is my childhood. I absolutely love the franchise. However, Diamond and Pearl was so disappointing and this series doesn't look any better. Sorry Pokemon; I've moved on with my life. ;_; I've watched a few episodes since it's been ported over to English and it's much imroved over the advanced generation. It seems that Pokemon has filled two of it's major holes, a strong female companion and a legitimate villain.
Kore wa Zombie desu Ka?: Cliche characters? Check. Bad jokes? Check. Lots and lots of over the top ecchi? Check. While it looks like this anime would give me a few laughs, just watching a review of it was painful. Definitely staying away from this one. I was roped into watching the first episode, and it wasn't as bad as I thought it would be, but there's little reason to watch this anime over the other shows on my priority list, so it's probably going to get burried.
Baby Princess 3D Paradise: I watched this review. What else needs to be said?
Ore no Imouto ga Konna ni Kawaii Wake ga Nai. (season 2) The first season was mediocre at best and I have no intention of watching the second season.
That's about it. I'll update this blog as I modify my "Won't Watch" list. If for any reason, I take an anime off the list, I'll justify that too.
