Hines misread boom's post, that's all. Whether he did it on purpose is debatable.
Boom was saying that "Ninja Gaiden is the bomb" (except he used a different word than bomb, which I can't repeat).
When Hines quoted it, he took out "the" and thus made it seem like Boom had said "Ninja Gaiden is bomb." Now if you substitute 'bomb' for what boom originally said, yes, it would like he had said that Ninja Gaiden sucked.
But that's not the case.
Anyway, just to clear it up.
Boom thinks Ninja Gaiden is awesome.
Hines does not.
End of story.
