I've never seen it YEt but you should watch it I heard its slow on the first two episodes and it picks up at the third I think???? ////

I saw th first two episodes and enjoyed it it but watch with caution I heard it gets scary

I will warn you that it has moe-like moments and that it will mess with you psychologically but it is a fantastic anime in my opinion.

It's pretty good - I have only seen the first two or three episodes, though.

Hehehe

It actually depends on if your into those type of anime and/or you can handle that type of stuff that shows up later on in the series(Not spoiling anything though)...

epic anime.

It's actually my favourite anime.

While being one of the most tragic animes of all time, it's a masterpiece. The story was amazingly well thought out. It's definitely a must-watch.
