No, not awesome I could think of a completely different word to describe it but it certainly wouldn't be awesome. As a matter of fact its one of the worst Naruto related theories I've ever heard. It also completely ignores the fact that Sasuke has strong will power, great chakra control, the sharingan and experience with high level genjutsu's all of which make him better against genjutsu.

-Plus he has seen Tsukiyomi before so he knows how it works and he may have MS himself.
