Zack has talked openly about his purpose for changing the costumes. He did so to juxtapose the Watchmen outfits with modern superhero movies. Because WATCHMEN is a movie, whereas the comic was a comic.
And you think he's what, lying about what he did?
You're asking me if he looks more bad-ass because he's a tool in armor than if he was a tool in spandex?
I guess that depends on if armor makes you look more badass. I don't think this armor does. I think he looks like a tool, period, in both versions. In a lot of ways the movie suit is even more pathetic than the book's, because he's clearly TRYING to look cool with all the overdesigned elements of his suit, but fails miserably to look either cool or intimidating.
