Just dislike how he ended up with no girl.
But from the last scenes he had with both girls they have a chance now, when he was unable to see them humans before.
His recovery make sense too, no bullshit deus ex machina plot.
It passed a long time from the end and there was no news, the anime and movie came too late to make spin offs, a sequel isn't impossible but it would require the author to make a new base for the world, not like Hitman Reborn changing from comedy to bullshit fights to save the mafia and the world, but something around that line.
