I have to go with cartoons on this one, based almost entirely off of my dislike for anime. Anime is just... terrible. That's a bit unfair, since I've not seen every anime, but I have seen many and, sweet fancy Moses, they have all been terrible. It's not for me in any way. I'm really not that in to most Japanese media, for various reasons, and anime just does nothing for me.
When I was younger, I watched things like Dragonball Z and Pokémon. Pokémon was just awful, everything in it was rubbish and annoying, but since everyone used to watch it, I kind of had to just to be able to socialise at school. Dragonball Z I actually kind of liked, but I was 9 years-old and it was about punching so of course I liked it. Once I was old enough to think, I realised what a load of bum it was. Ultimate Muscle, an anime about super powered wrestlers, came along at the end of my time with Dragonball Z and I watched it for a while since it was also about punching, but it was pretty naff. The only other animes I watched in that period were the likes of Yu-Gi-Oh (awful), Digimon (appalling), Beyblade (atrocious), Cardcaptors (abhorrent), and Tenchi Muyo which was about some kid who befriends a bunch of alien women and a cat that turned into a spaceship (or, to put it another way, abominable).
As I got older and 'found' the Internet and got a new circle of friends, I became exposed to more anime than before. Everyone seemed to love something I had already written off as trash, so I gave it another chance to win me over. A friend lent to me several DVD boxsets and each one was just pathetic: Escaflowne, Mobile Suit Gundam Wing, Neon Genesis Evangelion, Ghost in the Shell, Akira, the much lauded Cowboy Bebop, as well as a few others with names that I'll never remember, every one was just terrible. All of the clips, synopses, premises, and whatever else I have seen of perhaps hundreds of animes since have just reinforced my opinion that anime, as a media form, is just garbage. My cousin made me watch Halo Legends last week while I was babysitting (strange term, seeing as he's 15) and, my word, I never thought I'd hate something to do with Halo so much.
The problem for me is that anime is just so over-the-top, so fantastical, so off its cake, that it's utterly impossible to relate to anything going on in it. Even more mundane examples, like Shin-Chan, go so far into the realm of absurdity that it's not worth watching. They have no trace of reality in them and so I can't connect at all. Most of the time they value style over substance, putting a higher priority on looking 'cool' or 'cute' rather than telling a coherent story or developing believable characters. I just don't like it, at all, and I feel as though I have given it enough of a chance to know for certain that I won't find any that I like.
