You could use a noun with 何も to express your opinion that something doesn’t qualify as the said noun at all.
It is not a tragedy at all (although some may call it a tragedy).
It is not a good idea at all (although some may claim it to be).
With an i-adjective, you can say:
This book is not interesting at all.
It's not hot at all!
Keep in mind that i-adjectives don't take だ.
With a noun, for example you can say:
He has no faults at all.
I want nothing at all.
Use 何も only in the context of choosing one type of thing from many possibilities. ...
