So,

Spoiler:

Are we (almost) sure that Menma is a ghost or something like that or is it still arguable ?
Because I would prefer to see her alive.
The idea of the ghost is not bad but... I don't know i feel as if it is unnecessary. The plot is interesting enough without supernatural stuff. And the ghost who wants to see her friends happy together before leaving sounds a bit cliche in my opinion.
