This is one thing that doesn't bother me. At least in the Japanese version of most series, the boys actually sound the age that they're supposed to. In other words, it's realistic. This is my main gripe with dubs when it comes to boys speaking. They usually sound too old for their age or for their size. Yugi comes to mind for me. I've heard his dub voice, and he sounds way older than he should be. Of course this isn't always the case, even for originals, but as I mentioned, at least it's realistic that they use women who sound like pre-adolescent boys for like 12 year old male characters as opposed to having an adult male voicing them.

Beyblade is another series I didn't care much for voice wise. Our main five, Takao, Kon Rei, Max, Kai, and Kyouju sound realistic for the original because they're all 12 year old boys when it starts, yet, for the dub, Takao (Tyson), Kon Rei (Ray), and Kai all sound like adult males. Way too old given their ages.

Max and Kyoujuu (Kenny), however, both sound the ages that they're supposed to because both were voiced by kids and as the characters aged, so did the boys doing their voices, so they sounded more natural as the seasons went on.

Three way tie between Dubs, Filler, and those terrible endings that resolve nothing. The worst dub I've heard so far is Rurouni Kenshin (he sounds like he's either a young girl or a boy in the middle of puberty), worst filler of course is Naruto (I mean they actually had to start a new series just to move away from it!!), and I'll agree with everyone else and bash Inuyasha for its horrible ending (though Flame of Recca's also irritated me quite a bit, and Histories Strongest Disciple Kenichi stopped right before the best part). These three things are why I mostly just read manga now.

i hate when the anime ends before the actual manga plotline does, so they have to make up a "new" ending so they can end the anime. half the time it makes no sense and they reslove things in a stupid way.

I'll say it but you'll hate me for it.

I can't stand MECHA.

*runs away*

You know what just popped into ma' noggin? An anime revolving around the life of a mecha technician.

Seriously, how in the world do those things work? Besides, gotta' give props to the lil' guys every now and again.

When it ends in general.... I hate it when really good series ends. Like Trigun or Outlaw Star, or Cowboy Bebop. I hated it when those ended.

you have a fair point. people don't just find mecha while digging undergound (gurren lol) someone had to build them at some point. where do they get all that metal from and what factory is big enough to mold metal pieces of that scale?

Filler
Cliches
English Voice Acting

those are some of the most annoying things.

Whenever a cool supporting character has been reduced to standing back and stating the obvious!! Like what happened to Tuxedo Kamen-sama! He started out cool, then they had him show up, state the obvious, then leave! WHAT THE HECK IS THAT!!!???

Hmmm, like many other members I would have to say an ending in general is one of the worst things about anime for myself. You spend so long watching characters grow and develop & then BAM! It's all over >.<

And though sometimes dubs do get on my nerves, it's often less due to horrible voices themselves, but rather the changing of the dialogue. Such as with Generator Gawl "Man I love Cows!" XD
Not a good example, I'm more or less annoyed by censorship such as the usage of "monsters" rather than "demon".

Fans themselves I will admit can be nerve wrecking at times as well...

This is why I prefer the manga. His role was more significant, and bigger, for that.

I hate when the seiyu's voice sound so childish.. LOL

"Kill'em all" series
"bad" endings
terrible dubs(Voltron)
Americazation(robotech,Yugioh,Digimon,Pokemon)

And Why? x3 sometimes a bad ending is better than a good one. Unexpected, at least.

I'm too much of a sap...plus I feel empathy for alot of characters.(patheic I know:o )

oh yeah espically when they are squealing about yaoi. I also dont like fillers, dubs, and when it is advertized as in stores.:mad:

Since someone already mentioned bad dubs and demolition derby endings, excessive (and inappropriate) fan service, right off the top of my head.

most ger dubs

The one thing I absolutely HATE about anime is the ridiculous amount of annoying, selfish characters that get in the way of every relationship, and generally cause mayhem and chaos on a grand emotional scale.

Seiyuu can either make or break an anime series..

But sometimes the personality of the character can make me forget about the voice acting. ie. D Gray Man's Lavi.. I can't quite stand the voice acting but love Lavi :D

I don't like Mecha.. and hentai..

sorry but i got 3: bad voice actors, run-on scenes that last WAY longer than they should(naruto) and filler episodes-.->.<

I gotta say bad dubbing (Damn you 4kids!) and when series go for too long (One Piece has 376 episodes?!)

I'm going with most here...

english voice overs, more often then not, is the worst.

The fans.
20characters.

Crazy fan kids(I've read that in Japan, Otaku is pretty much an insult) filler, and pointless episodes that have absolutely nothing to do with the story(I'm talking about random, one here and one there, kind of things).

The skimptastic outfits- Can you say awkward?
They make me want to go crawl in a hole. >_<

The fact that the anime guys are so amazing and perfect. it makes real, human guys seem... not good enough.

bad dubbinng really annoys me.......

That R Al Fucking Perfect Even The Nerd And Ugly People!!.they R Like Prefect Ugly!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i know right? whenever i see that kinda stuff, i'm like, "Okay, awkward..." especially if i read with other people around. one time one of my friends picked up one of my books with THAT STUFF and she kept saying i was a pervert.

which I'm not. I like the story lines >_<.

the same applies to female

anyway i hate fan service if i want to see some 2d boobies i'd watch hentai

One thing that annoys me is why the talk for ages in the middle of a battle！e.g. Naruto and sumtimes bleach.

The fanbase.

I can agree on that one

You have agreed with me many times, Minimin.

Well if its the truth its easy to agree :)

Anime where there are frames of flowers popping out of nowhere.

When anime characters in a classroom learning English has a professor that has broken English. I mean, dude, it should not be that hard to find someone to read the English portion of the script. I would do it.
