>>1 OP for one it helps if there is a Manga/light novel to refer to as some people might be interested enough to read the manga/light novel before even committing to watch this anime when it comes out,
As the old saying goes "you can't judge a book by its cover" just like you can't judge an anime by it's art style, if the story is half baked then all it has it looks.
Secondly if you are going to make a thread for an anime it's best to have a *synopsis* which you can grab from any anime website or Wikipedia, "by copy and past", if you look at any other well made anime thread here it will have one.
In the opening thread post you can even go the extra mile by adding stuff like any well known "music artist, anime artist, voice actor, anime director an even the person who wrote the manga/light novel.
