Re: what the hell happened to Naruto's giant rasenshuriken.??
It is easy to explain,
Madara get actually hit by Giant FRS but:
1) Wood dragon was destroyed however while it was destroyed it absorbed chakra from FRS
2) Wood dragon get destroyed and then Madara used Preta Path almost instantly so he got no damage
3) Madara was wiped out along with wood dragon so he had to regenerate(But Kishi skiped it in fastforward manner) showing just Madara restrained by torii gates, so Hashirama could use Opening while Madara was regenerating.
