Then you don't mind if your manga got adaptation of another story in motion that not related to the original?

I really think that most people dont want a 100% filler story and there probbably are more bad examples of completely different story (i cant think of any because i dont watch bad anime series). Also, a lot of anime never see a second season so they have to make major cuts and often a filler end. sadly that's why I dont like a lot of endings to anime adaptations of running manga. lazy endings like hero doesn't end up with anyone and the story just goes on happens way too much unless the manga has already ended.

I'm sorry, I might have misunderstood your message, but if you're asking if I'm fine with an adaptation that is 100% different from the original, then yes, as long as it's good. I might argue, though, that it's not technically an adaptation if it's totally different, the two works must be at least tangentially similar (like in name, for example).

As for me... either the first or second. I'm leaning more to the first since a little bit can and sometimes WILL go a long way. A bad anime adaption that I recently saw (watched the first episode and couldn't sit through the second) would be Beelzebub. Was quite looking forward to it, too. As some one said (can't remember where or who) they made it a child's anime. It's not like they changed big things either (from what I could tell anyway) just some small things (but many of them). Not to mention the humour feels forced rather than spontaneous (don't ask how it just feel that way). But I digress, the majority of anime adaptions that been different (that I've seen) I wound up not liking.

Have we had it, or something close to it, on the site before?

I'm more of an original anime, or an "adaptation" that just take the character designs and go with something new, kind of guy. The majority of all adaptations tend to suck.

that would be 20th century then...

You do realize Evangelion was an animation before it was a manga right? Well, technically "chapter one" of the manga was released before "episode one" of the anime, but that was to promote the anime. It even says "Original Concept by Ganiax" on every cover. In short, the original story is actually the anime, and the adaption is the manga.

In any case, I've said this before on this site. I don't mind if liberties are taken. Why the hell would I want to see the same characters do the same exact thing? That said, if the characters don't act as I would expect them to act in these alternate adaptions, then we have problems. For example, I don't wanna see a Negima anime that features Negi as a well hung ten-year old systematically stealing the chastity of his equally pubescent female class, that suddenly grew 100 pounds of supple, virgin breast fat for the express purpose of "enhancing the plot". That would be silly.

Or how about a Kurokame anime that changes the main character from a barely redeemable drain on society to a boo-Hoo poor me emo teen. Oh wait... that one actually happened.
