Ack, that's so difficult to answer!
However, I can narrow it down to Death Note or Fullmetal Alchemist... or Black Butler... or D.Gray-Man... or Code Geass... Oh man, this is so impossible!
Oh man, this is a tough one. Trigun is my most favorite anime ever, but some of that has to do with nostalgia and warm associations. Gintama is definitely creeping up there, too. But then there's Cowboy Bebop, and Miyazaki films, and Millenium Actress....in the end, I think it might depend on what genre of anime we're talking about, and whether we're talking about personal preference or in some kind of objective sense.
I think it's too hard to choose ONE best anime ever, because there is such a large variety to choose from. Some people would choose some sort of Romance anime while another might choose a mecha.
For me, personally, it suppose it is a tie between Clannad: After Story, YuYu Hakusho, and FullMetal Alchemist: BROTHERHOOD. I don't see why Brotherhood's getting so much hate from fans. From what I've seen and know of the original anime, the plot of Brotherhood is superior. Eh, they both have they're good points. (Sorry, now I'm ranting...)
Hmm, I haven't watched a lot of anime, but from what I've seen, I'd say Evangelion. And Elfen Lied right after.
Ok so these are the ones I've enjoyed the most:
At the moment, because I've just finished watching it, I would say Tengen Toppa Gurren Lagann was my favourite, but my favourite changes often. However there is a bit of variety up there with the different types of story and what is included in them so I encourage everyone to check out their pages and watch some of them, I doubt you will be disappointed.
Asking difficult questions, are we?
There are a number of series and films which I really like and each has their own quality, so I'm just going to drop a list.
Best anime ever?
Well as a person question that is kind of hard, for about three reason.
1. The massive amount of anime that I have personally seen, makes the choice very difficult.
2. Most of the stories in Mainstream anime (i.e Naruto, Bleach, One Piece) are shallow and Filler is Killer
3. I am most prone to watch seasonal Anime (12-26 or so episodes), for the reason that The story is easy to understand and yet gripping and the characters are well thought out if only for a brief Series.
extra. 4. I am very bias the mecha anime, because the Gundam Series was the first anime that I watched and enjoyed.
So to answer that question, even though I gave a lot of back story, is a toss between Trigun, Gundam Seed (and Destiny) and Hell Girl.
the best anime movie i think is howl's moving castle
and then i think the best anime series is xxxholic - "mokona is mokona. you count them like this - one mokona, two mokona, and then you stop, 'cause there's only two."
Hard question! Now or ever? I guess the taste change with time, one of the best animes now would be Guilty Crown because I think the theme is really good so are the drawings and N6 is actually really good too.
But if a look back Inuyasha, One PIece and Nana were some of my favorites, and I was completely addicted to them! I liked Naruto too but I think they tried to make it way too large! And I'm still watching Fairy Tail and Darker than black!
Full Metal. :)
